Every Indexing API in One List: Google, Bing, Yandex, Naver
This list of indexing APIs gathers every practical way to notify search engines about new, updated, or removed URLs. It is for SEOs, developers, and publishers who want one reference for endpoints, auth models, quotas, and routing rules. You will finish able to choose the right API per content type, avoid the common mistake of sending IndexNow to Google, and operate all tracks from one clean intake.
Two facts frame the whole list. IndexNow is an open protocol co-developed by Microsoft Bing and Yandex that reaches Bing, Yandex, Naver, Seznam, and related supporters. The Google Indexing API is a separate Google only endpoint for JobPosting and BroadcastEvent pages that uses URL_UPDATED and URL_DELETED notices. Google does not support IndexNow. Keep those tracks separate in every plan below. Newcomers should first read the IndexNow complete guide alongside the Google setup notes before wiring any automation.
Key takeaways
- Google uses its own Indexing API plus sitemaps and Search Console flows, while Bing, Yandex, Naver, and Seznam share IndexNow.
- Each API has its own auth, quotas, payload rules, and retry behavior, so one shared sender cannot serve all.
- Sitemaps, canonical tags, and internal links remain the base that makes every API signal interpretable.
- Route by content type and host, pace per track, and log per URL with response codes.
- Test with one URL per track, join sends to fetches, stage bulk work over days, and review control peers monthly.

How to read this list of indexing APIs without mixing tracks
Read this list as two lanes plus companions, not as one universal endpoint. The Google lane covers Google only, with service account auth, per URL notices, and documented eligibility for JobPosting and BroadcastEvent pages. The IndexNow lane covers Bing, Yandex, Naver, Seznam, and related supporters, with key file auth and batched URL lists per POST. Companions include XML sitemaps, news sitemaps, RSS or Atom feeds, internal linking, and Search Console or Webmaster Tools submission features. Each lane has its own quotas and error codes, and each companion has its own refresh rhythm.
For every entry below, note five fields before you use it: endpoint or submission path, auth model, payload shape, quota and pacing expectations, and success meaning. Success means accepted or fetched, not ranked or permanently indexed today. Engines still apply quality, link, and relevance judgments after any notification. Teams that track accepted versus fetched versus impression movement read their systems correctly. Teams that equate a 200 response with ranking set themselves up for disappointment.
Keep hosts and canonicals strict across all lanes. Submit only fully qualified canonical URLs under verified properties, without fragments, session IDs, or tracking parameters. Keep www and apex consistent with canonical, keep locale variants on their verified hosts, and keep staging and preview hosts out of every sender. Dirty URL sets produce 422 style rejections on IndexNow, permission confusion on Google, and sitemap warnings everywhere.
Property strings cause a large share of cross API confusion. Search Console and Webmaster Tools treat protocol, subdomain, and path prefixes as distinct properties, so rights granted on one string do not cover siblings. Record the exact property string per host and lane in the runbook, confirm grants after every domain or protocol change, and test one URL per affected property before reopening bulk sends. This single habit removes a whole class of permission incidents. A nightly hygiene check that flags non 200, non canonical, noindexed, and redirected entries pays for itself within the first migration.
A small routing table prevents most misuse. Jobs and livestreams with valid markup go to the Google lane where eligible plus IndexNow where the host participates. General new and updated canonicals go to IndexNow plus sitemap refresh, with Search Console inspection for selected high value URLs rather than every page. Removals go to URL_DELETED where eligible plus redirects, removals tooling, and sitemap pruning. Feeds and sitemaps carry the steady state inventory while API lanes carry fresh change signals. Write this table once, review it quarterly, and require exceptions to carry an owner and an expiry date.
Control comparisons keep multi API reporting honest. For each major template, hold back a small matched sample from all lanes and compare time to fetch and time to impression against submitted peers. When submitted URLs move consistently sooner, current routing and pacing earn their keep. When both groups move together, normal crawling already covers that template and effort should shift to content depth, internal links, and sitemap quality. Publish the comparison monthly so budget debates use evidence rather than send totals.
Treat this page as an indexing api directory with an engine api comparison per lane, and keep a short seo api list in the runbook so new teammates learn which endpoint matches which content type.
Version awareness matters because docs evolve. Recheck the official protocol pages during each quarterly review rather than relying on a saved copy. The IndexNow documentation remains the source of truth for IndexNow fields and codes. Google Search Central remains the source for Indexing API eligibility and Search Console behavior. Bing Webmaster help covers Bing side submission and quotas. When sources disagree with older blog posts, including this one, follow the current official docs and note the change in your runbook.
Google Indexing API endpoint auth and quotas
The Google Indexing API exposes a publish endpoint that accepts URL_UPDATED and URL_DELETED notices for pages containing eligible markup, documented as JobPosting and BroadcastEvent inside VideoObject. Auth uses a Google Cloud service account with the indexing scope, plus ownership or full rights on the verified Search Console property. Calls go one URL per request with a short lived OAuth access token derived from the service account JSON. Responses return per URL status with timestamps that you can reconcile against crawl stats. Field level flow is described in the Google Indexing API usage guide.
Setup order matters more than speed. Create the Cloud project, enable the Indexing API, create the service account, download the JSON once to a vault, and delegate rights on the exact property string including protocol and subdomain. Test with one URL_UPDATED for a real eligible canonical page, confirm an accepted response, then watch for a fetch in server logs and Search Console. Only then connect CMS automation. Skipping the single URL test is the most common reason teams spend days debugging bulk failures that trace to a property mismatch or a disabled API.
Quotas are per project and per property in practice, with daily and per minute limits plus 429 backoff when exceeded. observed caps vary by account history and request patterns, so plan conservatively, pace sends across minutes, and stage large backlogs over days. Deduplicate repeats within 24 to 72 hours so ten edits to one posting produce one notice, not ten. Log notification type, timestamp, response code, and request identifiers per URL.
Clock and credential hygiene also belongs in the Google lane checklist. Server clock skew can break token exchange, revoked or deleted keys produce auth failures that look like quota issues at first glance, and disabled APIs return errors that resemble permission gaps. Check API enablement, key validity, grant scope, and clock health in that order before adjusting pacing. Log token refresh outcomes alongside send outcomes so the timeline shows whether auth or quota moved first. When 429 appears, pause only the Google lane, apply exponential backoff with jitter, honor any wait hint, and resume with lower concurrency. Never hammer the endpoint to catch up.
Eligibility honesty protects the property. Google documents narrow eligible types, not general blog posts or product pages. Many teams submit general pages and report faster discovery, but that use sits outside documented scope and carries policy and quota risk. A sound policy defaults jobs and livestreams to this lane, routes general pages to IndexNow plus sitemaps, and uses Search Console inspection selectively for high value general URLs instead of bulk API submission. If leadership asks why general pages do not all go through Google API, explain documented scope, quota cost, and the sitemap path in the same answer.
Error families are consistent. Permission failures point to Search Console delegation, property string mismatch, disabled API, or wrong scope. Token failures point to clock skew, revoked keys, or deleted projects. Quota failures point to pacing and backlog staging. A useful dashboard separates these three families with counts and sample URLs, links each to its fix checklist, and tracks time to recovery. For a deeper comparison of when this lane beats alternatives, see how IndexNow and the Google API compare.
IndexNow protocol endpoints and key model
IndexNow uses simple POST endpoints shared by participating engines, with host, key, and URL list fields in the JSON body. Auth is ownership proof through a key text file hosted at the site root, named after the key and containing the key as content. Engines verify by fetching the file, so it must stay public, fast, and stable across redesigns, migrations, and CDN changes. Up to 10,000 URLs ride in one request, split into sequential POSTs with pacing for larger batches. Accepted codes mean received, not indexed, with crawl and index decisions still made per engine.
Key lifecycle is the operational core. Generate a random string with a password manager, publish the file, confirm public 200 with exact content match, and enter the same key into every sender for that host. Recheck from an external fetch, not only from inside your network, and alert on redirects, robots blocks, firewall denials, or stale CDN caching. Rotate at least yearly or after staff and hosting changes, with an overlap window where old and new files both stay live until sends confirm on the new key. Record key name, hosts covered, deployment method, and rotation owner in one inventory page.
Payload hygiene decides acceptance rates. Send only canonical, indexable, fully qualified URLs under the verified host, with correct encoding and without fragments or tracking parameters. Exclude drafts, noindexed pages, soft 404s, and non canonical variants before send. Quarantine 422 cases for human review instead of retrying blindly, because one bad entry should not block thousands of good ones. Never resubmit unchanged URLs on a timer. IndexNow signals change, and engines discount noisy senders that ping steady state inventory as if it were fresh.
Response handling maps cleanly to fixes. Codes in the 200 range mean accepted. A 400 means malformed payload to correct and resend after validation. A 403 means key mismatch to fix at the file and host mapping. A 422 means invalid URLs to quarantine and clean at the source template or feed. A 429 means pacing to slow with backoff and smaller batches. Log batch ID, per URL outcome, and next action for every send. Join weekly with server log fetches from Bing and Yandex user agents to see whether accepted batches shortened time to fetch for your hosts.
Endpoint choice across participants stays simple for most teams. A single IndexNow POST reaches the shared participant set, so you do not need per engine IndexNow endpoints for routine work. Engine specific consoles still matter for sitemaps, verification, and diagnostics. Keep Bing Webmaster Tools and Yandex Webmaster verified alongside IndexNow so you can read crawl and impression movement per engine. Document which hosts participate, when each key file was last verified externally, and which sender owns each host.
Bing Webmaster URL submission API
Bing offers URL submission through Webmaster Tools alongside IndexNow, with separate quotas and flows that teams often confuse. Among url submission apis, IndexNow is the open ping path with key file auth and batched URLs, while all indexing apis for routine work still include this Webmaster path for targeted inspections. The Webmaster submission path is account and property based inside Bing Webmaster Tools, with its own limits and diagnostics. Use IndexNow for routine change signals and the Webmaster path for targeted inspections, sitemap management, and issue diagnosis. Track quotas separately, because hitting one limit does not imply the other is exhausted. Of the available index apis on the Bing side, these two cover most needs without extra vendors.
Verification and property hygiene come first. Claim exact hosts in Bing Webmaster Tools, keep sitemaps registered and clean, and confirm that key file fetches succeed from public paths. Submit changed canonicals through IndexNow, then use Webmaster Tools to confirm receipt patterns, crawl activity, and index coverage movement. When URLs lag, check URL inspection style diagnostics, robots fetch results, and sitemap warnings before increasing send volume. More pings rarely fix blocked fetches, thin content judgments, or canonical conflicts.
Quotas on the Bing side reward restraint. Space batches, deduplicate repeats, prioritize revenue templates and updated hubs during backlogs, and stage migrations over days. Log per batch outcomes and join with server logs for Bingbot fetches to read whether pings shortened discovery on your hosts. If submitted and control URLs fetch at similar times, shift effort to internal links, content depth, and sitemap quality before raising volume. If submitted URLs fetch consistently sooner without error growth, the current pacing is justified.
A frequent question is whether Bing submission helps Google. It does not directly. Bing side signals inform Bing powered surfaces, while Google reads its own API lane, sitemaps, links, and Search Console flows. Operate both lanes from one intake but measure them separately. Leadership rollups can sum accepted sends for simplicity, while operator dashboards keep per engine fetch and impression movement distinct so decisions stay grounded.
Common Bing side failures trace to host mismatch, stale key files behind CDNs, parameter laden URLs, and sitemaps full of redirects. Fix at the source template or edge configuration, then resubmit only the corrected canonicals. Keep a per host checklist with verification date, sitemap status, key file fetch result, and last bulk job so quarterly reviews catch drift before launches depend on the path. Add console links and named owners to the same row so any teammate can verify health in minutes.
Yandex Naver and Seznam paths through IndexNow
Yandex co developed IndexNow and reads the shared signal for faster discovery across its index, alongside Yandex Webmaster verification, sitemaps, and crawl diagnostics. Naver and Seznam participate through IndexNow as well, which gives international sites one POST path to several regional engines instead of separate per engine integrations. Coverage details evolve, so confirm current participant behavior on official protocol pages during quarterly reviews rather than hardcoding a stale list as exhaustive. For host level setup notes, the Yandex path is close to the Bing path: verify the property, host the key file, submit canonicals, and read webmaster diagnostics per engine.
Yandex Webmaster deserves the same care as other consoles. Verify exact hosts, register clean sitemaps, and monitor crawl and coverage sections for the property. Submit changed canonicals through IndexNow, then watch server logs for Yandex user agents and webmaster reports for fetch movement. Cyrillic and parameter handling need attention on multilingual estates: submit percent encoded canonicals, keep locale variants on verified hosts, and avoid submitting parameter switchers that canonicalize elsewhere. Quarantine patterns with elevated 422 rates usually point to feed or template encoding issues worth fixing once rather than retrying daily.
Naver and Seznam traffic patterns differ by market, but the submission mechanics stay uniform through IndexNow. Prioritize locale canonicals that serve those audiences, keep hreflang and canonical consistent, and stage translation backfills in priority order. Measure fetch and impression movement per locale rather than globally so one market issue does not hide behind healthy aggregates. Keep webmaster style verification where offered, even when IndexNow carries the routine signals, because consoles provide the diagnostic detail that raw response codes lack.
Regional edge and blocking issues surface here first. Country based rules, CDN edge filters, and firewall policies can allow origin checks while blocking engine fetches from specific regions. Verify key files and sample canonicals from external vantage points that match engine paths, and record per region results during onboarding and after edge changes. When one engine lags while others fetch promptly, compare robots fetch results, edge logs, and sitemap warnings per host before changing send volume.
Documentation discipline prevents drift. Record participant assumptions with dates, keep links to the official pages checked, and set a quarterly reminder to recheck with a named owner responsible for updating the runbook. Note any engine specific console steps alongside the shared IndexNow steps so new teammates follow one runbook instead of assembling fragments from old tickets. Small locales benefit most from this care because issues there stay invisible in global dashboards until launch week.
Sitemap pings and RSS as companion signals
Sitemaps remain the canonical inventory that makes every API ping interpretable across engines and consoles. Keep XML sitemaps current, split large estates with sitemap index files, and prune 404s, redirects, non canonicals, and noindexed entries promptly. Refresh lastmod honestly on real change rather than on every deploy, and keep sitemap URLs registered in Search Console, Bing Webmaster Tools, and Yandex Webmaster where offered. API lanes then carry fresh change signals on top of a trustworthy base instead of compensating for a dirty inventory.
RSS and Atom feeds serve a similar companion role for blogs, newsrooms, and catalogs with frequent updates. Keep feeds fast, valid, and limited to recent canonicals with correct timestamps. Use them for discovery alongside IndexNow rather than as a replacement for submission policy. Internal linking completes the trio by giving crawlers durable paths to changed hubs and new sections. A changed guide linked from the homepage and hub pages will be found through navigation even if a single ping is delayed.
The deprecated sitemap ping endpoints deserve a clear note. Google retired its sitemap ping endpoint, so modern Google flows use Search Console sitemap management, the Indexing API where eligible, and normal crawling guided by links and sitemaps. Sending repeated ping style GET requests to retired endpoints wastes effort and muddies logs. Update old runbooks and plugins that still reference retired paths, and point automation at supported lanes plus clean sitemaps.
Companion health checks belong in the weekly routine. Nightly sitemap validation with counts of flagged URLs, feed validation with item counts and timestamp sanity, robots fetch checks per host, and key file reachability per host form a compact dashboard. When an API lane shows elevated errors, read companions first: a sitemap full of redirects or a blocked key file often explains the pattern without any engine side mystery. Fix companions at the source, then resubmit only corrected canonicals.
Staging and hygiene rules apply to companions as well. Never register staging sitemaps in consoles, never expose staging feeds to public discovery, and never let preview hosts leak into production sitemaps. Promotion moves configuration and content, not hostnames. After migrations, re register sitemaps on new hosts, verify key files externally, and run ten live URLs per lane before reopening bulk sends. These steps feel slow once and save repeated incident weeks.
Choosing the right API per content type
Content type decides the lane, not habit or plugin defaults. Job postings with valid JobPosting markup and livestream pages with valid BroadcastEvent markup go to the Google lane where eligible, plus IndexNow where the host participates and the URLs are canonical. Breaking news benefits from news sitemaps plus IndexNow for supporting engines and Search Console inspection for selected Google URLs. General blog posts and guides go to IndexNow plus sitemap refresh and internal linking, with selective inspection for flagship updates. Product pages follow the same general path, with feed quality and availability markup doing more work than repeated pings.
Removals and merges need explicit handling across lanes. For removed eligible pages, send URL_DELETED where the lane supports it, apply redirects or 410 status correctly, prune sitemaps, and use removals tooling in consoles as needed. For merged pages, canonicalize to the surviving URL, update internal links, prune the retired canonical from sitemaps, and submit the survivor once through the appropriate lanes. Repeatedly pinging retired URLs keeps them in logs without helping coverage and can confuse reporting.
Volume and freshness set pacing per type. Hourly job feeds need deduplication and steady pacing with small concurrency. Daily editorial publishes need immediate single sends with collapse of rapid re edits. Weekly guide refreshes need one send per canonical after meaningful change, not per typo fix. Large catalog backfills need staged daily caps in priority order. Each type carries its own queue or priority class so urgent news never waits behind a catalog import. Document these classes in the routing table with owners and daily budgets.
A short decision worksheet keeps teams consistent. For each template, record content type, eligible lanes with reasons, host and locale mapping, change frequency, daily budget, and success metric such as time to fetch or time to impression. Review quarterly with SEO, engineering, and content operations. Retire lanes that show no lift against control peers and reinvest that budget in sitemaps, links, or content depth. The side by side lane comparison in how IndexNow and the Google API compare helps new stakeholders grasp why two lanes persist.
Edge templates need written exceptions. Paginated series submit the hub unless individual pages changed meaningfully. Faceted and filtered views stay out of all lanes. Translated pages submit per locale canonical with hreflang in place. Out of stock products submit once on status change rather than daily. Expired jobs leave feeds and sitemaps promptly with correct status and redirects where appropriate. Each exception carries an owner and a review date so temporary rules do not become permanent noise.
Operating all APIs from one intake
One intake feeding all lanes keeps operations legible at any size. Publish events from CMS webhooks, feeds, translation systems, and deploy pipelines enter a single queue with canonical URL, content type, brand and locale, change reason, and event timestamp. Normalization canonicalizes, strips parameters, checks 200 and indexability, and deduplicates within a window. Routing assigns lanes with reason codes. Pacing enforces per lane and per host limits with backoff. Logging records per URL outcomes for review. Editors publish normally while operators watch exceptions.
For a complete dual lane reference model, study the two API workflow covering Google and IndexNow together and adapt its queue, pacing, and logging patterns to your stack. Keep Google and IndexNow queues physically separate in code and dashboards even when they share intake, because auth, quotas, and retry rules never mix. Give bulk backfills their own lane so daily editorial sends stay fast during migrations. Require dry run validation for new sources before live sends.
Dry run mode deserves a permanent place in multi API operations. New CMS plugins, feed connectors, and deploy hooks should validate canonicalization, filters, batching, and logging without network sends for at least a few days. Promote to live per lane after a ten URL test with clean logs and visible fetches. This habit catches staging leaks, parameter regressions, and locale mapping errors before they consume quota or pollute reporting.
Weekly review follows a fixed script. Check send counts per lane and host against budgets, error rates by code, oldest queue age, key file status, delegation health, and sitemap warnings. Sample ten sent URLs per lane and confirm fetch or impression movement within days. Review quarantine and fix patterns at templates or feeds rather than resubmitting bad entries. Write one decision line per week with owner and date. Monthly, reverify key files externally, confirm grants on exact property strings, prune sitemaps, and review control comparisons of submitted versus held back URLs.
Incident handling stays calm with per lane runbooks. Auth spikes point to delegation or key files first. Quota spikes point to pacing, overlapping bulk jobs, and retry behavior. Quarantine growth points to templates or feeds emitting bad canonicals. Each runbook links to filtered logs for the affected lane and scope, with exact fix steps and rollback criteria. Practice with a tabletop review twice a year so response takes minutes during real launches.
Incident notes should record lane, scope, first symptom timestamp, overlapping jobs, and the exact fix with operator name. Over a few quarters these notes reveal repeat patterns such as Friday bulk imports colliding with editorial peaks or CDN changes preceding key file failures. Use the pattern list to set calendar guards and pre launch checks, which usually cut incident counts faster than raising quotas or adding senders.
FAQ
Which APIs should a small site use first?
Start with clean sitemaps plus IndexNow for supporting engines and Search Console flows for Google. Add the Google Indexing API only for eligible jobs or livestreams with valid markup. Test one URL per lane, confirm fetches, then automate publish triggers with deduplication. This order gives coverage without quota risk or complex infrastructure.
Does IndexNow submit to Google?
No. IndexNow reaches Bing, Yandex, Naver, Seznam, and related supporters through shared endpoints. Google uses its own Indexing API for narrow eligible types plus sitemaps and Search Console flows for general pages. Any claim that one IndexNow ping covers Google contradicts current engine support and should be treated as a warning sign.
When should the Google Indexing API be used?
For JobPosting pages and BroadcastEvent livestream pages with valid markup on verified properties. General blog posts and product pages belong to IndexNow plus sitemaps and links, with selective Search Console inspection for flagship URLs. Routing by content type keeps quota spend aligned with documented eligibility.
How do quotas differ across these APIs?
Google quotas apply per project and property with per minute and daily limits plus 429 backoff. IndexNow quotas apply per host and key with batch caps and pacing expectations. Webmaster submission paths carry their own separate limits. This submission api overview shows why indexing endpoints must be tracked per lane, so stage bulk work over days and never hammer endpoints to catch up after a pause.
Do sitemaps still matter when using APIs?
Yes. Sitemaps carry the canonical inventory that makes pings interpretable, and they remain the main path for general Google pages. Keep them current and clean of 404s, redirects, and non canonicals. For teams comparing search engine apis list options and search api options for companions, use API lanes for fresh change signals on top of that base, not as a replacement for inventory quality.
How should bulk lists be staged across APIs?
Deduplicate to canonicals, prioritize revenue templates and updated hubs, and split IndexNow into sequential POSTs within batch caps while spacing Google notices across minutes. Run bulk lanes separately from daily editorial sends, check budgets at 70 percent, and measure fetch movement per stage before raising daily volume.
