Rate Limiting
Rate Limiting for Hiro APIs
The following rate-limits (in requests per minute, or RPM) are applicable for all Hiro APIs as of November, 2023:
API Rate Limits
| API key | Rate Limit |
|---|---|
| No | 50 requests per minute (RPM) per client IP, for unauthenticated traffic |
| Yes | 500 requests per minute (RPM), with an authenticated API key, regardless of origin IP |
These rate-limits apply across our 3 public-facing APIs:
The entirety of API traffic, regardless of whether it's from one or all of these APIs, will be attributed to a single default quota: 50 RPM for unauthenticated and 500 RPM for authenticated traffic.
These new rate limits help us ensure fair usage of Hiro APIs and provide the best possible service as our community of developers and applications grow.
