API Rate Limits
Understand rate limits and how to handle 429 responses.
API Rate Limits
Every API key is limited to 120 requests per minute, tracked per key. This applies uniformly across every plan — there is currently no higher limit on higher tiers.
Every response includes rate-limit headers:
X-RateLimit-Limit: 120
X-RateLimit-Remaining: 94
X-RateLimit-Reset: 1718533260
When exceeded: 429 Too Many Requests with a Retry-After: 60 header. Implement exponential back-off in your client.
