## 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 deepvoice-guard-mcp-574364c6 -d '<json body>'
```

Example prompt: Can you check this voice recording for me and tell me if it's a real human voice or an AI deepfake — here's the audio data encoded as a string.

## When to prefer this

Choose this endpoint when you need to verify whether a voice recording is real or AI-generated, particularly in fraud prevention, identity verification, or content authenticity workflows. Prefer this over general audio analysis tools when the specific concern is deepfake or voice synthesis detection.

## Known failure modes

- Malformed or empty 'data' string returns a validation error
- Non-audio data passed as string may produce unreliable results
- Very short audio clips may yield low-confidence or inconclusive results
- Unsupported audio encoding formats may cause processing failures
- Rate limiting or payment issues may result in 402 or 429 errors
