Rate Limiting
Two-layer rate limiting protects the API — per-IP and per-organization.
Tier limits
| Tier | Burst rate |
|---|---|
| Free | 10 req/s |
| Starter | 25 req/s |
| Growth | 50 req/s |
| Business | 100 req/s |
| Scale | 250 req/s |
| Enterprise | 500 req/s |
Business+ tiers can exceed their burst and pay overage. Lower tiers receive HTTP 429 when they exceed their limit.
