  title: Payable API
  description: >-
    REST API for integrating with Payable programmatically. Authenticate with
    Clerk JWT (web app) or API keys (`esk_live_` / `esk_test_`). Test keys
    operate in sandbox mode without wallet charges or real WhatsApp. Request

    class-transformer DTOs. Every error is RFC 9457 `application/problem+json`;
    branch on `code`, not `detail`.
