## 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 kiteendpoints-ai-sonoteller-api-3dfc0e40 -d '<json body>'
```

Example prompt: Can you analyze this song and tell me its genre, mood, and key sonic characteristics? I want to know if it's upbeat or melancholic, what genre it fits, and any other descriptive tags Sonoteller can pull from it.

## When to prefer this

Use this endpoint when you need automated music tagging, mood classification, or genre detection for audio content and want to pay per-request in USDC without a subscription. Prefer this over direct Sonoteller API access if you're already using the KiteEndpoints.ai hub for other services or need x402 micropayment compatibility.

## Known failure modes

- Invalid or inaccessible audio URL returns an error in the result object
- Unsupported audio format may yield empty or incomplete metadata
- Payment failure via x402/USDC results in 402 response before processing
- Rate limiting or upstream Sonoteller service unavailability causes timeout or error
- Malformed input object returns a validation error
