How it works

Public index and catalog routes that use the public limiter allow 60 requests per minute per IP address.
The public limiter runs before optional API-key authentication, so sending a key does not replace this limit with a per-key tier. Requests from origins configured as trusted by Ornn bypass the public limiter; this is deployment configuration, not a general client entitlement. See Authentication for which endpoints are public.

​
When you exceed the limit

After the enforced allowance is exhausted, the limiter returns HTTP 429 Too Many Requests with a JSON body stating the 60 requests per minute allowance. Use the response’s Retry-After header to determine how many seconds to wait before retrying.
Back off when you receive a 429; repeated public polling should be cached client-side or moved to a server-side cache.

​
Avoiding rate limits

  • Cache values you read repeatedly. The GPU index only updates hourly, so there’s no benefit to polling faster than that.
  • Batch where possible. For example, GET /api/daily-index/all returns every GPU in one request instead of one call per model.
