# Rach Developer Docs

> One platform for crypto payments, programmable wallets, stablecoins and swaps.

## Two products, two API keys

Rach has **two independent APIs**, each with its **own base URL and its own API key**.
A Payments key does **not** work on CaaS, and a CaaS key does **not** work on Payments.

|                | Payments (Gateway, WaaS, Swap, …)                       | CaaS (Stablecoins)                                  |
| -------------- | ------------------------------------------------------- | --------------------------------------------------- |
| **Base URL**   | `https://api.rach.finance/api/v1/`                      | `https://api.rach.finance/caas/api/v1/`             |
| **Key prefix** | `test_sk_…` / `live_sk_…`                               | `rach_sk_test_…` / `rach_sk_live_…`                 |
| **Header**     | `X-API-Key`                                             | `X-API-Key`                                         |
