# Get API Access

## Free public endpoint

A public DART endpoint is available for testing and low-volume use. No API key required.

**Base URL:** `https://api.titan.exchange/dart`

* **1 request per second** per IP address
* REST only, JSON responses
* DART provider only

***

## Partner access

For higher rate limits, pass your API key via header:

```bash
curl -X POST https://api.titan.exchange/dart/swap \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ ... }'
```

Or using `X-API-Key`:

```bash
curl -X POST https://api.titan.exchange/dart/swap \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ ... }'
```

To request a partner API key, fill out the application form:
