## 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 citiview-kya-know-your-agent-trust-check-4d046250
```

Example prompt: Before we send any payment, can you run a trust check on this agent wallet 0x1a2b3c4d5e6f... — I want to see its x402 payment history, whether it's OFAC-sanctioned, and what risk score it gets?

## When to prefer this

Use this endpoint when an AI agent needs to assess the trustworthiness of an unknown counterparty wallet before executing a payment or entering into an automated transaction. It is the best choice when you need a combined view of x402 payment history, OFAC compliance, wallet maturity, and seller registry status in a single call rather than assembling these checks manually from separate sources. Prefer it over generic blockchain explorers when you specifically need agent-economy signals like x402 spend history and Coinbase seller directory membership.

## Known failure modes

- Invalid or malformed wallet address returns a 400 error
- Wallet address not on Base network may return no data or an error
- OFAC screening service unavailability could degrade results
- Wallet with no on-chain history may return minimal data with low confidence
- Rate limiting or payment failure (x402 $0.009 USDC not settled) returns 402

## How this service works

Know Your Agent: trust check on an agent's wallet before you transact with it. x402 payment history matched against every seller in Coinbase's x402 directory (payments, USDC spent, sellers, last payment), wallet age, smart wallet or key, balances, OFAC sanctions screen, listed seller status, and a risk score with a plain verdict.

## Output

Returns a structured report including: x402 payment history (number of payments, total USDC spent, unique sellers transacted with, timestamp of last payment), wallet age, wallet type (smart wallet or key-based), current token balances, OFAC sanctions screen result, whether the wallet is a listed seller in Coinbase's x402 directory, a numeric risk score, and a plain-English verdict summarizing the overall trustworthiness of the agent.
