Rate limits & errors

  • 30 requests/minute and 500 requests/day per IP. Exceeding either returns HTTP 429 with a Retry-After header.
  • All responses are JSON with the envelope { "ok": true, "data": {...} } on success or { "ok": false, "error": { "code", "message" } } on failure.
  • code values are stable; safe to switch on programmatically. message is human-friendly and may change.
