Rate limits

600 requests per minute, per account, across every endpoint — the same limit regardless of which paid plan you're on. There's no separate, lower limit for any tier today.

Going over the limit

A request past the limit gets 429 Too Many Requests with a Retry-After header (seconds until the window resets):

HTTP/1.1 429 Too Many Requests
Retry-After: 42
X-RateLimit-Limit: 600
X-RateLimit-Remaining: 0
X-RateLimit-Reset: 1784629200000

{"error": "Too Many Requests"}

Avoiding it

If you're polling for new responses, switch to webhooks instead — a push on every new response costs zero requests against this limit.
