Every developer request authenticates with a sandbox API key as a Bearer token:Versioning
All endpoints are under/v1. Breaking changes ship under a new version prefix.
Response format
Success responses return the resource directly (no envelope). Errors return a standard bilingual envelope:Endpoints
The Endpoints section is generated from the OpenAPI spec and includes an interactive playground. Today it covers the livePOST /v1/callback, plus GET /v1/calls and GET /v1/health. Callback lifecycle endpoints (GET/DELETE /v1/callbacks/:id, GET /v1/callbacks) are marked coming soon until they ship.
