Integrate sanctions screening into a payment gateway

Add real-time sanctions screening before payment authorization.

Integration pattern

async function processPayment(payment) {
    // Step 1: Screen counterparty
    const screen = await fetch(
        `https://sanctionsai.dev/sanctions?wallet=${payment.wallet}`
    );
    const result = await screen.json();
    
    // Step 2: Block if sanctioned
    if (result.blocked) {
        await logBlock(payment, result.matches);
        return { status: "blocked", reason: "OFAC_MATCH" };
    }
    
    // Step 3: Proceed if clean
    await logScreen(payment, "clean");
    return await executePayment(payment);
}
