## Before you call it

1. Set `duration` (default 8 seconds) and `model_version`. The default is stereo-melody-large
2. Use `Prefer: wait` for short clips and webhooks for long ones
3. On a 429, wait the reset time in the message, about 30 seconds
4. Switch to `google/lyria-2` or `minimax/music-2.5` when output must be commercial
5. Add a payment method first, or you're held to 6 requests a minute
