# Translate a transcript into many languages with cue-accurate captions, and optionally dubbed audio.

> Priced per language-minute. One request can be twenty languages of a ten-minute cut — two independent multipliers, so both move the price.

    The priced, versioned public API. Every call authenticates with a workspace
    API key (`Authorization: Bearer sk_live_…`), names the project it files its
    output under, and reports what it cost. `GET /v1/capabilities` answers what
    this deployment can serve right now and at what price; anything it reports
    as unavailable answers 503 `capability_unavailable` rather than 404.
