X Rate Limits

Published X API v2 rate limits, transcribed from X's own per-endpoint tables on 2026-08-28. This file REPLACES a 2026-05-04 scaffold that carried invented tier numbers (10 rpm free / 100 rpm pro / 1000 rpm enterprise); X does not rate-limit by tier at all — limits are per-endpoint, per-app and per-user, on 15-minute or 24-hour windows.

X Rate Limits is the machine-readable rate-limit profile for X on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 17 rate-limit definitions.

The profile also includes 4 backoff/retry policies defined and response codes documented for throttled, quotaExceeded, serviceUnavailable, and error_body.

Tagged areas include Rate Limiting, Quotas, and Throttling.

Policies

Backoff Strategy
X's own guidance: on 429 read x-rate-limit-reset, implement exponential backoff, cache responses, and spread requests across the window.
Prefer streaming over polling
X recommends the filtered stream rather than polling search endpoints for real-time data, explicitly as a rate-limit strategy.
Usage cap
Pay-per-usage accounts are capped at 3,000,000 Post reads per monthly billing cycle. Exceeding it returns 429 with problem type usage-capped. Higher volume requires an Enterprise agreement.
Separate limits per product
X API v2, the Enterprise APIs and the Ads API each have their own rate-limit regimes; Enterprise limits are set by contract.
