PostHog API Rate Limit: Per-Key Caps by Endpoint Type

PostHog rate limits its private endpoints, mainly per personal API key. Analytics endpoints get 240 requests per minute and 1,200 per hour, the query endpoint 2,400 per hour, and other create, read, update and delete endpoints 480 per minute and 4,800 per hour. Public capture and flag endpoints aren't rate limited.

The quickest way to tell whether PostHog's limits apply to you is to ask one question: is the request authenticated with a personal API key? PostHog itself gives that as the rule of thumb. Event capture from your website or app doesn't use one, so it isn't limited at request level. Scripts that pull data out with a personal key are.

Public versus private endpoints

Private GET, POST, PATCH and DELETE endpoints are rate limited. Public POST-only endpoints, such as event capture and /flags, aren't. Most limits count per personal API key, not per team, and OAuth and logged-in sessions don't count against these personal API key limits.

Hosts differ by region. US Cloud uses us.i.posthog.com for public endpoints and us.posthog.com for private ones; EU Cloud uses the eu equivalents.

Limits by endpoint type

ItemLimitApplies to
Analytics endpoints (insights, persons, session recordings)240/minute and 1,200/hourPer personal API key
events/values60/minute and 300/hourPer personal API key; event_name required
Query endpoint2,400/hour, plus an hourly read allowancePer personal API key
Feature flag local evaluation600/minutePersonal API key in SDKs
Prompt fetches600/minute, separate allowancePersonal API key
Other CRUD endpoints480/minute and 4,800/hourPer personal API key
Invites50/hour and 200/day, up to 20 per bulk requestPer organization, including invites from the PostHog UI
Public capture and /flagsNo request-level rate limitPublic POST-only endpoints

The hourly caps matter as much as the per-minute ones. 1,200 analytics requests an hour works out at 20 a minute on average, so a script that runs flat out at 240 a minute will use the whole hour's allowance in five minutes. If a job has to run all day, pace it to the hourly number, not the per-minute one. The same goes for other CRUD endpoints: 4,800 an hour is 80 a minute sustained, well below the 480 burst.

The analytics limit is the one most scripts meet first. A job that pulls insights or persons in a tight loop will hit 240 a minute long before anything else, so pace those calls.

Unlimited doesn't mean unprotected

PostHog Docs add a qualification to the public endpoints. Capture and feature flag evaluation have no request-level limit, but they still apply per-distinct-ID ingestion protection and report quota limiting in the quota_limited field. If that field shows up in responses, data is being limited for a reason other than request rate. And because OAuth requests don't count against personal API key limits, an integration built on OAuth sits outside the table above.

What happens at the limit, and what PostHog suggests

PostHog isn't offering higher limits. Instead, it points to three routes for getting more data out: its Endpoints product, batch exports, or file download exports. If you're pulling large volumes for a warehouse or dashboard, a batch export is usually a better fit than hammering the API. For one-off analysis, a file download export avoids rate limits entirely.

  • Pace analytics requests to stay under 240 a minute.
  • Use the query endpoint for heavier questions, within its 2,400 an hour.
  • Move bulk extraction to batch exports.
  • Consider OAuth for integrations, since it doesn't draw on personal key limits.

How other APIs count requests

Counting rules differ a lot between tools. Front's API rate limit starts at 50 requests per minute and is enforced per company rather than per token. Asana allows, as of Nov 2026, 150 requests per minute on Free domains and 1,500 on higher-tier domains, per token. PostHog's per-key approach means two colleagues with their own keys don't share a pool, which isn't true of Front.

My advice for scripts that talk to PostHog

Check whether each script really needs a personal API key, and give separate jobs separate keys so they don't compete. Keep analytics calls under 240 a minute, push bulk pulls to batch exports, and watch for quota_limited on capture responses. You'll rarely see a rate-limit error if you design around those four habits.
