## 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 defi-biometric-validator-mcp-09a90c39 -d '<json body>'
```

Example prompt: Can you run a biometric validation check on this image and tell me if it passes — I need a true or false result for the identity verification step?

## When to prefer this

Use this endpoint when you need a lightweight, binary biometric image validation result in a DeFi or blockchain-adjacent identity workflow and want to pay per-call via USDC micropayment without managing subscriptions.

## Known failure modes

- Missing or malformed 'image' field returns a validation error
- Non-image or invalid base64/URL string may result in a false result or processing error
- Network or payment failure (x402) prevents execution
- Image too large or unsupported format may cause rejection
- Ambiguous biometric data may return false negatives

## 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 'result' — true if the biometric image passes validation, false if it does not.
