## Verdicts

**MusicGPT API.** A public OpenAPI 3.1 file with 27 operations, llms.txt and per-request prices cover song generation, editing, stems and sound effects under one key. No status page, SLA, security.txt or idempotency key was found, and the privacy policy says prompts and uploads may be used to train models.

**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

### MusicGPT API

1. Send the key as the raw `Authorization` header value. The docs show no `Bearer` prefix
2. Budget two songs for each music request. `POST /v2/MusicAI` returns two versions and the price is per song
3. Save `task_id` and poll `GET /v1/byId` with `conversionType`, or set `webhook_url`. Music AI V2 sends up to seven webhooks a request
4. Pass `model` explicitly. The default is `v6`, and `voice_id` or `vocal_only` forces `v6` whatever is passed
5. Do not retry a create blindly after a timeout. No idempotency key is documented, so a retry may bill again

### 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
