## 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 pxbt-x402-music-generator-ed8e3a86
```

Example prompt: Generate a 45-second upbeat lo-fi hip-hop track with jazzy piano and soft drums — something good for studying.

## When to prefer this

Choose this endpoint when you need to programmatically generate short custom music tracks (10–120 seconds) from a natural language description and can pay per-call in USDC on Base via the x402 protocol. It is well-suited for agents building creative pipelines, content automation, or media production tools that require AI-generated audio without a subscription.

## Known failure modes

- Missing or empty 'prompt' query parameter returns a validation error
- Duration ('sec') outside 10–120 range may be rejected or clamped
- Payment failure or insufficient USDC balance results in a 402 Payment Required response
- Network or generation backend errors may result in a failed job status at the status_url
- Polling the status_url may show a failed or timed-out job if the generation service is overloaded

## How this service works

Paid agent API: USDC on Base via x402.

## Output

Returns a JSON object with a job_id string, a status string (e.g. 'queued'), and a status_url pointing to a polling endpoint where the agent can check progress and retrieve the final audio once generation is complete.
