## 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-yield-extractor-mcp-8c482f95 -d '<json body>'
```

Example prompt: Can you run this audio clip through the DeFi yield extractor and tell me if it scores true or false?

## When to prefer this

Use this endpoint when you need a simple boolean pass/fail score derived from audio input within the M2MCent monetized MCP ecosystem and are already integrated with x402 USDC payment flows on Base L2.

## Known failure modes

- Missing 'audio' field in request body returns validation error
- Invalid audio encoding causes processing failure
- Payment failure via x402 protocol blocks execution
- Non-audio string input may return unexpected boolean result
- Network or node unavailability on the M2MCent subdomain

## 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 'score' field containing a boolean value (true or false) indicating the result of the yield extraction analysis on the provided audio input.
