Get API key

Reference

Rate limits

Requests per minute and the headers that report them.

Each API key can make 120 requests a minute. REST and MCP calls made with the same key share that allowance.

Headers

X-RateLimit-Limit header
Requests allowed per minute.
X-RateLimit-Remaining header
Requests left in the current minute.
Retry-After header
On a 429: seconds to wait before trying again.
X-RateLimit-Reset header
On a 429: when the limit resets, as a Unix timestamp.

Over the limit

Requests over the limit get 429 with {"message": "Too Many Attempts."}. Wait for Retry-After seconds, then try again. When retrying a post, keep the same Idempotency-Key.

Other limits

  • Up to 50 accounts and 20 media files in one post.
  • Media files up to 60 MB.
  • Posts scheduled up to 1 year ahead.
  • Each platform’s own limits on text, images and video, listed on its platform page.
