## 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 omnicall-musicgen-text-to-music-api-77604245
```

Example prompt: Generate a royalty-free instrumental background track for a relaxing nature documentary — something calm, orchestral, and cinematic — using the MusicGen API.

## When to prefer this

Choose this endpoint when an agent needs to generate a royalty-free instrumental audio track on-demand from a natural language description without managing API keys. Ideal for media bots, content creators, and creative agents that need pay-per-call music generation with no subscription overhead. Best suited when MusicGen-style instrumental output is acceptable and the agent can pay $0.03 USDC per call via Base or Solana.

## Known failure modes

- Invalid or missing 'input' query parameter returns an error
- Vague or unsupported prompt may produce unexpected audio styles
- Payment failure (insufficient USDC balance) returns HTTP 402 and blocks generation
- Network timeout during model inference if generation takes too long
- Rate limiting or capacity issues may return 5xx errors

## How this service works

Text-to-music — short royalty-free instrumental track generated from a prompt (MusicGen). Pay-per-call USDC, no API key. For content, media, and creative agents.

## Output

Returns a URL pointing to a generated royalty-free instrumental audio file that matches the text prompt description, synthesized by MusicGen. The agent receives a direct link to the audio track ready for playback or download.
