Aegis KYT is an AML data service for AI agents. Hit an endpoint with no credentials, get a quote, sign a x402 payment authorization, retry — pay-per-call, settled on Base. No accounts. No KYC. No API keys.

​
Why x402

Most data APIs gate access behind subscriptions, key issuance, and per-route rate limits — friction that AI agents can’t navigate autonomously. x402 turns the HTTP 402 status code into a stateless protocol:
  1. Agent requests the resource.
  2. Server replies 402 with a stablecoin quote (asset, amount, recipient, expiry).
  3. Agent signs an EIP-3009 transferAuthorization for the quoted USDC.
  4. Agent retries with X-PAYMENT: <base64 proof>; server verifies, settles, and serves the resource.
Replay-protection, multi-chain, $0 onboarding cost. See Authentication for the full flow.

Powered by

  • 44 ingest sources continuously refreshed: OFAC SDN, UK OFSI and EU sanctions lists, Tether and Circle blacklists, GraphSense tagpacks, hack-attribution databases, our own curated VASP registry, and licensed commercial intelligence that informs the score without being exposed.
  • ~795,000 label claims across 11 EVM + non-EVM chains.
  • Aegis 4-tier consensus: SDN exact match → 100+-source consensus → 1-hop inheritance from neighbours → BFS multi-hop exposure with per-category aggregation.
