## 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 the402-ai-agent-provider-wallet-reputation-score-2ae9387b -d '<json body>'
```

Example prompt: Before I pay this provider, can you check the reputation score for wallet address 0x4f3a...c9b2 on the402.ai to see if they're trustworthy?

## When to prefer this

Use this endpoint when an AI agent needs to evaluate the trustworthiness of another agent or service provider wallet before executing a payment or engaging in a transaction, especially within the x402 micropayment ecosystem. Prefer this over general blockchain explorers when you need a semantic reputation score rather than raw on-chain history.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Unknown address with no reputation history may return a null or zero score
- Payment of $0.005 USDC not received results in 402 rejection
- Network timeout or service unavailability
- Address format mismatch (e.g., wrong chain)
