## 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 edtech-biometric-validator-mcp-d6f6ef40 -d '<json body>'
```

Example prompt: Can you validate this audio recording as a biometric sample for the edtech system and tell me if it passes verification?

## When to prefer this

Use this endpoint when you need a lightweight, binary pass/fail biometric audio validation specifically within an edtech context and require gasless USDC micropayment settlement via x402 on Base L2. Prefer this over general-purpose voice authentication APIs when integrating with MCP-compatible educational platforms.

## Known failure modes

- Missing or malformed audio field returns validation error
- Audio data in unsupported format may cause processing failure
- Empty or too-short audio sample may return false status
- Network or payment settlement failure returns HTTP 402 or 5xx
- Ambiguous audio quality may produce inconsistent boolean results

## 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 containing a single boolean 'status' field indicating whether the provided audio biometric passed validation (true) or failed (false).
