Example use cases
Pre-transfer sanctions check
“I'm about to send ETH to 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — can you quickly check if that wallet is on any OFAC sanctions list before I proceed?”
DeFi counterparty compliance
“Our DApp is about to interact with wallet 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B — please screen it against the OFAC SDN list and tell me if it's a PASS, WARN, or BLOCK.”
Automated payout pipeline screening
“Before we release payouts to contractors, check whether the wallet 0x71C7656EC7ab88b098defB751B7401B5f6d8976F is sanctioned so we can flag any risky ones before transferring funds.”

Endpoint
GEThttps://lion-x402-bible.lionmaster-operations.workers.dev/api/x402/wallet-screen-json?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need instant, low-cost ($0.001) OFAC SDN screening for a single EVM wallet address before executing a crypto transaction, onboarding a counterparty, or releasing a payment. Prefer this over manual lookups or full KYC bundles when you need a fast PASS/WARN/BLOCK signal without the overhead of a full compliance suite. Ideal for autonomous agents that need keyless, micropayment-gated compliance checks at transaction time.
Side effects
- Invalid or malformed wallet address format returns an error response

- Network or Cloudflare Worker downtime causes unavailability
- Payment of $0.001 USDC on Base via x402 must succeed or the request is rejected
- Non-EVM addresses (e.g. Bitcoin, Solana) may not be supported
