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 web3-biometric-simulator-mcp-d76fa3a6 -d '<json body>'
```

Example prompt: Run a web3 biometric simulation on this image and tell me if it passes — just give me a true or false result.

## When to prefer this

Use this endpoint when you need a simple pass/fail biometric simulation from an image in a Web3-native, pay-per-call context using USDC on Base L2 via the x402 protocol. Prefer it when you want a minimal API surface (image in, boolean out) without managing complex identity infrastructure.

## Known failure modes

- Missing or malformed image input returns a validation error
- Non-image or corrupt base64 data may cause processing failure
- Payment failure via x402 protocol results in 402 response and no execution
- Network timeout if the MCP node is temporarily unavailable
- Ambiguous image quality may yield 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 field indicating whether the submitted image passes the biometric simulation check (true = passes, false = fails).
