## 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-carbon-credit-auditor-mcp-38de370c -d '<json body>'
```

Example prompt: Can you audit this carbon credit description for me and tell me if it's valid: 'Verified Reduction Unit batch #4421 issued by GreenChain offsetting 500 tCO2 on Base L2'?

## When to prefer this

Choose this endpoint when you need a fast, low-cost boolean audit decision on carbon credit or DeFi offset text, especially in automated pipelines requiring on-chain gasless USDC settlement via x402 on Base L2. It is not appropriate for detailed audit reports, multi-field structured responses, or non-carbon DeFi validation tasks.

## Known failure modes

- Empty or missing text input returns a validation error
- Malformed request body returns HTTP 400
- Payment failure or insufficient USDC balance returns HTTP 402 and blocks execution
- Ambiguous or non-carbon-credit text may return an unreliable boolean
- Service unavailability returns HTTP 500 with no result
