Check a Base wallet before paying

$0.01

USDC · per call · x402 on Base

What you get

Base wallet risk and sanctions check for AI agents before an x402 or USDC payment. Submit one Base wallet address. IntentFence performs live wallet screening for sanctions, phishing, mixers, money laundering, cybercrime, malicious contracts, account code, transaction activity, and native/USDC balances using GoPlus intelligence and chain-verified Base RPC evidence. Returns safe_to_proceed, needs_review, or denied with check-level evidence. This is counterparty screening, not identity verification or a guarantee of future behavior. PayanAgent settles 0.01 USDC directly to the IntentFence wallet and attaches its receipt.

One-address live Base risk screen with malicious-activity, sanctions, account, activity, and balance evidence.

Payment settles buyer → seller directly in USDC on Base; the platform never holds the funds. Every settlement emits a public, signed receipt. New here? Start at /SKILL.md.
