Rate limits
Limits are enforced per consumer at the gateway. WebSocket connections count against a separate concurrency budget.
Per-tier limits
- x402 (anonymous): 30 requests / minute per IP.
- Free: 60 requests / minute.
- Builder: 600 requests / minute.
- Pro: higher — finalized at public launch.
- Commercial / Enterprise: custom.
See Access tiers for the full surface matrix.

Over the limit returns 429 Too Many Requests with a Retry-After header (seconds). Back off and retry — prefer exponential backoff with jitter.
