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-optimizer-mcp-node-532268cb -d '<json body>'
```

Example prompt: Run the DeFi biometric optimizer MCP node with my parameters string and return the analysis result — pay the ~$0.24 USDC fee via x402 on Base L2.

## When to prefer this

Choose this endpoint when you specifically need a DeFi biometric optimization computation delivered via a monetized MCP node with gasless USDC micropayment settlement on Base L2, and a simple boolean analysis output is sufficient for your workflow.

## Known failure modes

- Payment failure: insufficient USDC balance for x402 settlement returns 402 Payment Required
- Invalid parameters: malformed or missing 'parameters' string returns 400 Bad Request
- Node unavailability: MCP node offline or overloaded returns 503 Service Unavailable
- Network error: Base L2 settlement timeout causes delayed or failed response

## 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 'analysis' indicating whether the DeFi biometric optimization computation produced a positive or negative result.
