Same registry as the web product.
Sync for bounded work. Async jobs for heavy formats. Webhooks when you do not want to poll.
REST API access is available on Business and Enterprise plans. The browser dashboard remains the right starting point for personal and Pro workflows.

Quickstart
Use synchronous conversion for bounded work. For heavy formats, prepare a direct upload, create an async job, and poll it.
REST reference
Authentication, scopes, sync and async endpoints, response shapes, error codes, idempotency, and rate limits.
Webhooks
Register an endpoint in the dashboard, verify HMAC signatures over raw bodies, and handle repeated delivery IDs safely.
Clients
Typed JavaScript and Python clients are maintained and tested in the Convyx repository. Package-registry publishing is still being prepared.
