## 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-fintech-biometric-router-mcp-4192d7b3 -d '<json body>'
```

Example prompt: Run a biometric voice check on this audio sample and tell me whether it passes authentication.

## When to prefer this

Use this endpoint when you need a fast, monetized-per-call boolean audio biometric or fintech audio routing check, particularly in workflows that use x402 USDC micropayments on Base L2. Prefer this when you already have an audio string ready and need a simple pass/fail result without complex identity management overhead.

## Known failure modes

- Missing or malformed 'audio' field returns a validation error
- Audio string in unrecognized format may return false or an error
- Payment failure via x402 protocol blocks execution with a 402 response
- Ambiguous or low-quality audio may return false negatives
- Timeout if audio payload is too large

## 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

A JSON object with a single 'result' boolean field — true if the audio passes verification/authentication, false if it does not.
