promptrequiredstringDescribe the song: genre, instruments, BPM, key, mood. Use [Verse], [Chorus] and [Bridge] tags or [0:00 - 0:10] timestamps to shape the structure, paste your own lyrics, or add "instrumental only, no vocals" for a backing track. Lyrics come back in the language you prompt in.
"Create a 2-minute dreamy indie pop song about a summer road trip, in G major at 118 BPM, with bright acoustic guitar, warm vocal harmonies and a wide chorus.\n[Verse]\nDriving down the coastal line, radio static and sunshine\n[Chorus]\nWe are the echoes in the night, burning brighter than the light"image_urlsoptionalstring[]Optional reference images. Lyria 3 accepts up to 10 and composes music inspired by their mood, colour and subject.
[]Response Type
Returns: Audio
Asynchronous requests (v2)
Use Async for video, long-running (>~60s), or high-concurrency workloads; Sync is simplest for fast image & LLM calls. Async submits a request and you poll it to completion.
- 1
POST /v2/lyria-3-proSubmit — returns request_id, status_url, response_url
- 2
GET /v2/requests/{id}/statusPoll — until COMPLETED or FAILED
- 3
GET /v2/requests/{id}Result — final response body
Status states
- A FAILED request is served as HTTP 422 — the body still carries the error detail.
- An unknown or expired request_id returns HTTP 404.
- Results are retained for 1 hour, then expire.
- Content / RAI blocks surface as FAILED, not a separate state.
- Track completion by polling the status endpoint.
