Referencia de la API

Limits are enforced over a fixed one-hour window per account — the window opens with your first request and resets one hour later. It does not slide continuously. The allowance depends on your plan.

Read the response headers rather than hard-coding a number or a reset time: your allowance can change with your plan, and X-RateLimit-Reset always carries the exact reset moment.

Present on every successful response:

• X-RateLimit-Limit — your hourly allowance.
• X-RateLimit-Remaining — requests left in the current window.
• X-RateLimit-Reset — when the window resets, as an absolute Unix epoch time in seconds, not a countdown.

When the limit is exceeded the API returns 429 with a Retry-After header, in seconds, and this body:

{
  "error": "RATE_LIMIT_EXCEEDED",
  "message": "API rate limit exceeded for this account (<limit> requests/hour). Retry after <n>s."
}

The two headers do not overlap: on a 429, X-RateLimit-Reset is not set — use Retry-After. On a successful response, Retry-After is not set.

If you need to react to changes promptly, use outbound event webhooks instead of polling. They deliver within seconds and consume no API quota.
