- aid: chainalysis:sanctions-screening
  name: Chainalysis Sanctions Screening API
  description: 'Free public REST API that returns whether a given crypto address is identified as sanctioned by OFAC, EU,
    or UN sanctions authorities. No commercial licence required; widely embedded by wallets, dApps, and exchanges to block
    sanctioned addresses at the perimeter. Requires a free API key supplied in the X-API-Key header - probed 2026-08-27, an
    invalid key returns HTTP 401 {"message":"Invalid API Key"}. Chainalysis ships the same sanctions data in a second, separate
    form: a permissionless on-chain oracle smart contract exposing isSanctioned(address), deployed across Ethereum, Polygon,
    BNB Smart Chain, Avalanche, Optimism, Arbitrum, Fantom, Celo, Blast, and Base, which needs no API key at all. The go.chainalysis.com
    document below covers the ORACLE; the REST reference is inside the gated developer portal.'
