Every API key includes the full surface — cross-venue search, unified schema, and the supported venue pass-through. Limits are per API key and apply across both hosts (api.pmxt.dev and trade.pmxt.dev) — see hosts.

​
Limits

Limits apply per API key across both hosts (api.pmxt.dev and trade.pmxt.dev). Credit accounting: 1 REST call = 1 credit, 1 WebSocket message = 0.1 credits. Health checks are free.

​
Rate limit responses

When you hit a limit, the API returns 429 Too Many Requests with the window and retry timing. The SDKs handle short bursts automatically with exponential backoff.

​
Usage dashboard

Every request shows up under Usage > Request Log with endpoint, status, and latency. The same counts power the quotas — what you see is what’s being counted.
