Generate a new media item from a text prompt: text-to-video, text-to-image, image-to-video, or a programmatic Manim animation (generator 'auto' picks the best one for the prompt). Async — returns a media id that flips to ready when generation finishes; poll GET /media/:id or register a media.completed webhook. Priced on what the model actually costs; refused with 402 if your balance cannot cover the quote (see GET /me).
Get authoring context for a media item (faces + transcript + beat/word grids) GET
The read-only context an agent needs to author a composition over this source: the detected face/subject roster (face-0 = primary speaker, with normalized bbox + active-speaker share), the transcript, the temporal grids — `beatGrid` (a MUSIC bed's rhythm: bpm, beatTimesMs in milliseconds, confidence, method) and `wordGrid` (VO word-onset timings in milliseconds, from the transcript) — and a presigned `thumbnail` (~the footage at a glance). For stills at CHOSEN timestamps, call preview_frame with a one-clip composition over this media. Call this before authoring crop intents (reframe) and overlay/caption timing. Faces are lazily detected — `faces.status` is `not_detected` until a compose/detect pass has run over the source, never a faked empty roster. `beatGrid` is null until beat analysis has run: generated music beds are analyzed automatically at delivery; an uploaded/imported bed may not carry a grid yet (on-demand analysis is not client-triggerable today). `audioRole` is the DECLARED role of an audio asset (vo | music | sfx | ambience) — author the clip source's `audioRole` from it; `envelope` carries the coarse `envelopeClass` (transient | sweep | ambient) plus any probed attack/centroid/volume stats. Both are null for footage/images or an undeclared audio asset.
