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.
Example use cases
Secure voice login anti-spoofing
“A user is trying to log in with their voice — run liveness detection on this audio clip to make sure it's a real live speaker and not a pre-recorded or synthesized replay before granting access.”
KYC voice identity verification
“I need to verify that this submitted voice sample is from a genuine live human as part of our onboarding KYC process — check it for biometric liveness and return an authenticity score.”
Clone and verify voice for synthesis pipeline
“Take this voice audio data, clone it for our synthesis model, and confirm the source sample passes liveness checks so we know it came from an actual human speaker and not a spoofed recording.”

Endpoint
POSThttps://api.m2mcent.com/voice-cloning-biometric-liveness-mcp/api/processWhen to prefer
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.
Side effects
- 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
