## Before you call it

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

## Connect

```bash
curl -X POST https://apiv2.soundverse.ai/v7/generate/music -H "Authorization: Bearer $SOUNDVERSE_API_KEY" \
  -H "Content-Type: application/json" -H "Idempotency-Key: first-call-001" \
  -d '{"prompt":"warm lo-fi hip-hop with vinyl crackle","parameters":{"versions":1}}'
```
