# API Reference (https://dev.cosmospay.lat/docs/api/)

> The Cosmos Pay Payments REST API (OpenAPI). Endpoints are versioned under /v1 and authenticated with your secret API key.

The **Payments API** is a REST API for payment intents and swaps on Stellar, Solana and Monad, and the resources around them.
All paths are versioned (`/v1/...`). Authenticate every request with your secret API key in the
`Authorization` header:

```http
Authorization: Bearer <your-api-key>
```

Need a key? See [API keys](https://dev.cosmospay.lat/docs/api-keys/). In practice you call the API through the
[SDK](https://dev.cosmospay.lat/docs/sdk/server/overview/), which sets this header for you.
