## 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-proptech-voice-synthesis-auditor-mcp-86c643c8 -d '<json body>'

Example prompt: Can you audit this proptech voice synthesis query and tell me if it passes: 'Generate a listing narration for a 3-bedroom condo in downtown Austin at $450,000'?

## When to prefer this

Choose this endpoint when you need a fast pass/fail audit gate specifically for proptech (real estate) voice synthesis content. It is appropriate when your workflow requires a boolean validation signal before publishing or processing property-related audio content. Not suitable when you need detailed scoring, multi-dimensional feedback, or non-proptech audio validation.

## Known failure modes

- Missing required 'query' field returns validation error
- Empty or malformed query string may return false score
- Payment failure via x402 protocol results in 402 response blocking execution
- Ambiguous or out-of-domain query may yield unreliable boolean result
- Network timeout on the MCP node returns no response
