# Rate Limits

> How much traffic your API key gives you.

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](/authentication#hosts).

## Limits

| Endpoint | Per-minute | Per-month |
| -------- | ---------- | --------- |
| `/v0/*`  | 60         | 25,000    |
| `/api/*` | 60         | 25,000    |

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.
