Each API key is limited to 120 requests per minute (a fixed window). Every response includes the current budget:
HeaderMeaning
X-RateLimit-LimitMax requests per window (120).
X-RateLimit-RemainingRequests left in the current window.
When you exceed the limit, you get 429: 
{ "error": { "code": "rate_limited", "message": "Too many requests." } }

​
Handling limits

  • Watch X-RateLimit-Remaining and slow down before you hit zero.
  • On a 429, back off and retry after the window resets (≤ 60s).
  • Batch where you can — a single POST /posts can target many channels at once.
