## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability compacthost-ai-music-generator-ca72f7ea -d '<json body>'
```

Example prompt: Generate a 45-second upbeat lo-fi hip-hop track with the lyrics 'morning light, coffee in hand, the city wakes up slow' — I want it to feel relaxed and jazzy.

## When to prefer this

Choose this endpoint when you need to generate a complete music audio file (MP3) on-demand from a text description, with optional lyrical content and a configurable duration — particularly in automated pipelines that can handle pay-per-call USDC micropayments via x402 on Base. It is well-suited for agents that need to produce background music, jingles, or ambient soundscapes without a subscription. Prefer it over text-to-speech endpoints when the output should be musical rather than spoken, and over video generation endpoints when only audio is needed.

## Known failure modes

- Invalid duration outside 15-240 second range returns an error
- Prompt or lyrics too long may be rejected or truncated
- Payment failure via x402 (insufficient USDC balance) results in 402 response and no audio
- Generation timeout for longer durations may result in no response
- Ambiguous or empty prompt may yield generic or low-quality output
