Up and running in 2 minutes

Install the SDK, initialize, and call verify(). That's it.

import { Kontext } from 'kontext-sdk';

const ctx = Kontext.init({
  projectId: 'my-agent',
  environment: 'production',
});

const result = await ctx.verify({
  txHash: '0xabc...',
  chain: 'base',
  amount: '0.50',
  token: 'USDC',
  from: '0xAgentWallet',
  to: '0xAPIProvider',
  agentId: 'research-agent',
});

// result.compliant = true/false
// result.checks = [{ name: 'OFAC Sanctions', passed: true }, ...]
