Compliance Screener

The Compliance Screener checks blockchain addresses against sanctions lists, known fraud databases, and risk scoring services. Use it before processing transactions to flag high-risk addresses and maintain regulatory compliance. The screener is available as a public API — no authentication required.

Screen addresses before sending funds or accepting deposits:

// Before sending funds
const screen = await fetch('https://crypto-api.yativo.com/api/v1/screener/check', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({ address: recipientAddress }),
});
const { data } = await screen.json();

if (data.risk_level === 'critical' || data.risk_level === 'high') {
  throw new Error(`Address ${recipientAddress} is flagged: ${data.risk_level}`);
}

// Safe to proceed with the transaction
