Rate limits

Every API key is limited to 60 requests per minute, flat — the same limit for every account, on every endpoint under /v1. There are no per-plan tiers and no response headers reporting your remaining quota — if you need to stay under the limit, count your own requests client-side.

Proxy traffic through generated connection lines isn't affected by this limit at all — it only applies to calls against the management API itself (account, plans, generate, top-up).

Handling 429s

Exceed the limit and you'll get:

HTTP/1.1 429 Too Many Requests
{"error":"Rate limit exceeded — 60 requests/minute"}

Back off for a few seconds and retry — the window resets on a rolling 60-second basis per key.
