# Payments API Reference

> Every public Rach Payments endpoint, with live "try it" and code samples.

This reference is generated from the Rach Payments OpenAPI specification, so it always
matches the live API. Endpoints are grouped by product in the sidebar; each has request
and response schemas, multi-language code samples, and an interactive request runner.

## Base URL

```
https://api.rach.finance/api/v1/
```

## Authentication

Every endpoint uses your Payments API key in the `X-API-Key` header. See
[Get your API keys](/guides/api-keys) and [Test vs Live](/guides/environments).

  Admin and internal operations are intentionally **not** part of this public reference.
