# Voice Cloning Biometric Liveness MCP

> Voice Cloning Biometric Liveness MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-14).

Performs voice cloning combined with biometric liveness detection to verify that a voice sample is from a live, authentic human speaker

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 voice-cloning-biometric-liveness-mcp-5ab2882b -d '<json body>'
```

Example prompt: Check this voice recording to verify it's from a live person and not a replay or synthetic spoof — run biometric liveness detection and tell me if the speaker is authentic.

## When to prefer this

Choose this endpoint when you need to combine voice cloning with biometric liveness verification in a single call — particularly for anti-spoofing in authentication pipelines, KYC flows, or anywhere you need to confirm a voice comes from a real live speaker rather than a replay or synthetic source.

## Known failure modes

- Invalid or missing audio data in the 'data' field returns an error
- Low-quality or too-short audio clips may result in inconclusive liveness scores
- Heavily compressed or corrupted audio may fail processing
- Network timeout for large audio payloads
- Ambiguous liveness result when background noise interferes with voice signal

## 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 structured result containing liveness detection outcome (live/not-live), biometric verification confidence score, and optionally a cloned voice representation derived from the input audio data.
