## 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 legaltech-voice-synthesis-monitor-mcp-d2c14bb7 -d '<json body>'
```

Example prompt: Can you check this audio recording and tell me whether the voice in it is AI-synthesized or real — I need to know for a legal review?

## When to prefer this

Choose this endpoint when you need a fast, binary classification of whether an audio recording contains AI-synthesized or real voice, particularly in legal, compliance, or evidentiary contexts where a simple true/false determination is sufficient.

## Known failure modes

- Missing or malformed 'audio' field returns a 400 or validation error
- Audio data in unsupported format may produce incorrect predictions
- Payment failure via x402 protocol results in 402 response blocking execution
- Empty or very short audio strings may yield unreliable boolean predictions
- Network timeouts on the remote MCP node result in no response

## 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 a single boolean field 'prediction' — true if the audio is detected as synthesized/AI-generated voice, false if it appears to be authentic.
