# 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

| Plan       | Monthly credits | Per-minute | WebSocket streams | Price                                  |
| ---------- | --------------- | ---------- | ----------------- | -------------------------------------- |
| Free       | 25,000          | 60         | 5                 | \$0/mo                                 |
| Starter    | 250,000         | 300        | 20                | \$29.99/mo                             |
| Pro        | 1,000,000       | 1,000      | 100               | \$99.99/mo                             |
| Enterprise | Custom          | Custom     | Custom            | [Contact us](https://pmxt.dev/pricing) |

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.
