Twitter Rate Limits

X API v2 enforces rate limits on top of its pay-per-call pricing. Limits are scoped per endpoint with per-app (Bearer) and per-user (OAuth) buckets, typically over 15-minute or 24-hour windows. Headers expose the live limit, remaining, and reset timestamp. When a limit is exceeded, the API returns HTTP 429 with error code 88 ("Rate limit exceeded"); recovery is via the reset timestamp and exponential backoff.

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

It captures 13 rate-limit definitions, measuring requests_per_15_minutes and requests_per_24_hours.

The profile also includes 5 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Social Media, Developer API, and Rate Limiting.

Policies

15-Minute / 24-Hour Windows
Most endpoints reset on 15-minute windows; high-volume actions (post creation, DM creation, media upload init) use 24-hour windows. Use x-rate-limit-reset to determine wait time.
App vs User Buckets
Each endpoint has separate per-app (Bearer) and per-user (OAuth) buckets; choose the auth context that fits your traffic shape and treat them as independent budgets.
Error Code 88 Recovery
A 429 response carries error code 88 ("Rate limit exceeded"); recover by waiting until x-rate-limit-reset and applying exponential backoff before retrying.
Streaming for Real-Time
For high-volume real-time use cases, prefer streaming endpoints over polling to stay within the 15-minute / 24-hour windows.
Caching and Distribution
Cache responses, monitor remaining, and distribute requests across the time window to avoid bursting against the limit.
