How this service works
KYC identity for AI agents. Pay once with USDC on 6 networks, verify your wallet, and get a permanent on-chain attestation every x402 API can read. No accounts, no repeated sign-ups.
Output
Returns a JSON object with: `sanctioned` (boolean — true if matched, false if clean), `matchCount` (number of distinct sanctioned entities matched), `matches` (array of matched entity details including caption, countries, entityType, topics, and datasets), and `walletAddress` (the queried address). An empty `matches` array with `sanctioned: false` indicates a clean wallet.
Example use cases
DeFi protocol compliance before transfers
“Before I execute this swap, can you verify that the recipient wallet 0x742d35Cc6634C0532925a3b844Bc9e7595f42b1E isn't sanctioned so we don't run into regulatory issues?”
Solana validator onboarding screening
“We're about to add a new validator to our stake pool with this Solana address. Run a sanctions check on it first to make sure we're not delegating to anyone on a blocklist.”
Cross-chain payment counterparty verification
“Our payment processor is about to send USDC across three networks to this address. Can you quickly screen it against global sanctions so we know it's safe to proceed?”
Technical details
Endpoint
GEThttps://kyc.madhousewallet.com/api/public/kyc/sanctionsWhen to prefer
Use this endpoint when you need real-time sanctions screening for an EVM or Solana wallet address before executing a transaction, onboarding a counterparty, or establishing an AI agent identity. Prefer this over manual OFAC lookups when operating in a programmatic, agent-driven context where low per-call cost ($0.02 USDC) and on-chain attestation via the x402 protocol are required. Ideal for DeFi, payments, and compliance workflows that need machine-readable, structured sanction match data without requiring account setup.
Side effects
- Invalid wallet address format — returns error if address is not a valid 0x EVM or base58 Solana address
- Payment failure — $0.02 USDC x402 payment not confirmed, request rejected
- Network unavailable — underlying sanctions data provider unreachable
- Missing wallet parameter with no paying wallet context — cannot determine address to screen
