## Verdicts

**SOUNDRAW API.** Trained only on in-house compositions, per SOUNDRAW. No public API docs, OpenAPI spec, SDK or changelog.

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

## Before you call either

### SOUNDRAW API

1. Needs a contract and token before any call. There's nothing to probe anonymously
2. Save generated files within 72 hours. The links expire and songs are deleted
3. Don't let end users resell raw tracks. The licence restricts it

### Soundverse API

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