| Limit | Value |
|---|---|
| Every API key | 100 requests / minute, across all routes |
| Invoice routes, per account and per IP | Invoice calls only: a write (create, cancel, switch) is refused above 100 a minute, a read above 200 (one counter for both) |
| New EVM invoices per client | 60 attempts / minute per client (your account + IP + User-Agent + your X-Client-Id header, if you send one). Going over blocks that client for 60 seconds |
| All authenticated requests, per account | Free plan: 120 / minute; paid plans higher |
| Webhook deliveries | 3 attempts per event |
A limit answers 429 with a Retry-After header: the seconds to wait, an upper bound — a retry may succeed sooner.
