## 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-voice-synthesis-validator-mcp-a02ff197 -d '<json body>'
```

Example prompt: Run a validation check on this voice synthesis query for my metaverse project: 'high-fidelity avatar speech synthesis for real-time NPC interaction in a virtual environment' and tell me if it passes.

## When to prefer this

Choose this endpoint when you need a lightweight boolean validation of a voice synthesis query in a metaverse context and require a simple pass/fail signal. It is most appropriate when you already have a query string ready and need rapid, low-cost validation rather than full synthesis or generation. Prefer alternatives if you need the actual synthesized audio output, detailed error diagnostics, or non-metaverse voice validation.

## Known failure modes

- Missing required 'query' field returns a validation error
- Empty or malformed query string may return false for analysis
- Payment failure via x402 protocol results in 402 status and no response body
- Network timeout on the MCP node returns no result
- Overly long query strings may be rejected or truncated

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a JSON object with an 'analysis' boolean field indicating whether the submitted query passed the voice synthesis validation check (true = valid/passes, false = invalid/fails).
