## 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 m2mcent-metaverse-sentiment-synthesizer-mcp-69b9a7b9 -d '<json body>'
```

Example prompt: Analyze this audio clip for metaverse sentiment — pass the audio data and give me back the synthesized sentiment result URL.

## When to prefer this

Choose this endpoint when you need to synthesize sentiment specifically from audio input in a metaverse or virtual-world context and are operating within an x402 USDC micropayment workflow on Base L2.

## Known failure modes

- Missing 'audio' field returns validation error
- Malformed or empty audio string may produce an error or empty result
- Payment failure via x402 protocol prevents execution
- Schema inconsistency: response declares 'url' as boolean which may cause parsing issues
- Network timeout on the remote MCP node

## Output

Returns a JSON object with a 'url' field (boolean type as declared in schema, though likely intended as a URL string) pointing to or representing the synthesized sentiment result.
