Rate limits

Requests are rate limited per key. The default is 60 requests per minute; a custom limit can be set on a key. Every response carries the current limit state.

X-RateLimit-Limit: 60
X-RateLimit-Remaining: 58
X-RateLimit-Reset: 1717619400

When you exceed the limit you get 429 Too Many Requests with a Retry-After header (seconds to wait):

HTTP/1.1 429 Too Many Requests
Retry-After: 12

{ "error": "Rate limit exceeded. Slow down and retry shortly.", "retryAfterSeconds": 12 }
