## 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 metaverse-carbon-credit-synthesizer-mcp-audio-validation-b5988971 -d '<json body>'
```

Example prompt: Run this audio clip through the metaverse carbon credit synthesizer validator and tell me whether it passes — just need a true or false result.

## When to prefer this

Use this endpoint when you need a binary true/false evaluation of an audio input within a metaverse carbon credit MCP workflow and are operating on the x402 payment protocol on Base L2.

## Known failure modes

- Missing or malformed audio field returns validation error
- Non-string audio value causes schema rejection
- Payment failure via x402 protocol results in 402 response and no processing
- Oversized audio payload may cause timeout or rejection
- Empty string audio input may return false or error
