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 m2mcent-defi-biometric-predictor-mcp-10c150e4 -d '<json body>'
```

Example prompt: Run a DeFi biometric predictor check on this scenario: 'Is this user's biometric signature consistent with their on-chain trading pattern?' and give me a true or false answer.

## When to prefer this

Choose this endpoint when you need a fast, cheap boolean answer to a DeFi biometric question and are operating in an x402 payment-enabled agent environment on Base L2. It is suitable for lightweight yes/no classification tasks in DeFi biometric contexts where a full LLM reasoning chain would be too expensive or slow.

## Known failure modes

- Missing required 'prompt' field returns a 400 validation error
- Payment failure or insufficient USDC balance results in a 402 Payment Required response
- Ambiguous or malformed prompt may still return a boolean but with low reliability
- Network or node downtime may return a 503 Service Unavailable
- Rate limiting on the MCP node may return a 429 Too Many Requests

## 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 containing a single boolean field indicating whether the predicted outcome of the submitted prompt is true or false. No additional explanation or confidence score is provided.
