# AllScale Open API

> Accept stablecoin payments and send payouts through the AllScale Open API.

The AllScale Open API lets your platform take stablecoin payments from buyers and
send funds out to recipients, without holding crypto infrastructure yourself.

Every request is authenticated with an HMAC-SHA256 signature derived from your
store's API key and secret — start with [Authentication & Request Signing](/api-reference/authentication).
