## 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 ddg-reputation-score-39f45ac4 -d '<json body>'
```

Example prompt: Can you get a reputation score for this entity — I need to know how trustworthy they are before we proceed, and I'm happy to pay the $0.01 USDC fee via x402.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call reputation score for a specific entity and are operating in an environment that supports x402 micropayments with USDC. It is well-suited for AI agents that need bounded, single-artifact reputation results without requiring a full account relationship with a reputation provider. Prefer this over free or subscription-based alternatives when you need verifiable, on-demand scoring with crypto-native payment settlement.

## Known failure modes

- Payment not received or x402 handshake fails — request rejected before processing
- Malformed request body — missing required 'input' or 'output' fields returns a validation error
- Unknown or unsupported entity identifier — may return ok:false or an error payload
- Provider backend unavailable — upstream timeout or 5xx error
- Insufficient USDC balance or unsupported chain for payment
