Rate limits

Each endpoint allows 60 requests per minute from a single IP address. Exceed that and you get an HTTP 429 response instead of the usual success payload.

Every response carries headers telling you how much budget is left for the current minute:

X-RateLimit-Limit: 60
X-RateLimit-Remaining: 40

Once the limit is reached, the response tells you when to try again:

Retry-After: 11            # seconds
X-RateLimit-Reset: 1669844631   # unix timestamp
