## 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 agentrxi-know-your-agent-kya-trust-check-a1b76b7f
```

Example prompt: Before I send payment, can you run a trust check on this agent wallet 0x1234abcd... on Base — I want to know its risk score, whether it's OFAC-sanctioned, and what its x402 payment history looks like?

## When to prefer this

Use this endpoint when you need to vet an AI agent's wallet before engaging in a financial transaction, onboarding it to a platform, or delegating work to it — especially when you want a combined view of OFAC compliance, x402 payment history against Coinbase's directory, wallet maturity, and a ready-made risk verdict rather than assembling those checks separately.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Wallet address not found on Base chain may return empty history with low trust score
- OFAC screening service unavailability could cause partial results
- Rate limiting or payment failure at $0.009 USDC per call if micropayment not processed

## 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 on the agent wallet including: x402 payment history (payments made, USDC spent, sellers transacted with, last payment date), wallet age, wallet type (smart wallet or key-based), current balances, OFAC sanctions screen result, listed seller status in Coinbase's x402 directory, a numeric risk score, and a plain-language verdict summarizing the overall trust assessment.
