$0.08 a full song on lyria-3.5 and $0.04 a 30-second clip, flat. No free tier for Lyria, so billing is needed before the first call.

Songs with vocals, instrumentals, stems (2, 6 or 12), SFX and remix behind one endpoint. No status page, changelog or security.txt.

Draft on lyria-3-clip-preview at $0.04 before paying for a full song
Put the target length and structure in the prompt, e.g. "[0:00 - 0:10] Intro" or "a 2-minute song"
Decode output_audio.data from base64 straight to a file. Don't let it into the context
Don't name artists or paste song lyrics. The safety filter blocks the request
Back off exponentially on 429 RESOURCE_EXHAUSTED. Limits are per project and tier

Always set Idempotency-Key on creates, so a retry after a 429 doesn't bill twice
Retry only errors with retryable: true (RateLimited, DependencyUnavailable). 401 and 403 won't fix themselves
Pass license explicitly. The default is 1, royalty-free, which doesn't cover sync or distribution
Fetch audio through GET /v1/files/{file_id}/download, then poll GET /v1/generations/{id} or open /stream for progress
