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.
Example use cases
Pre-payment counterparty screening
“I'm about to pay an agent at wallet 0xAbCd...1234 for a service — can you run a KYA check on it first and tell me its risk score, sanctions status, and whether it's a verified seller in the x402 directory?”
Automated agent fleet trust gate
“Before my orchestrator agent sends USDC to any downstream agent, check the wallet 0x9f8e7d...5678 for OFAC flags, wallet age, and x402 payment history so I know it's safe to whitelist.”
Unknown agent due diligence
“An agent just reached out to me claiming to be a trusted data provider — can you look up its wallet 0x2b3c4d...ef01 and give me a plain verdict on whether it looks legitimate based on its payment history and risk score?”

Endpoint
GEThttps://agents.citiviewgroup.com/v1/kya?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
