Before you call either
Mubert API
- Search the library before generating. A match costs no generation
- Pick a pre-rendered duration (5, 6, 8, 10, 15, 20, 30, 40, 60, 180, 240 or 300 seconds) for a one-request result
- Download tracks straight away. URLs expire after 900 seconds by default
- Treat stream URLs as secrets. They carry the customer access token
SOUNDRAW API
- Needs a contract and token before any call. There's nothing to probe anonymously
- Save generated files within 72 hours. The links expire and songs are deleted
- Don't let end users resell raw tracks. The licence restricts it
