    • Screen: Screens the provided input against various government sanctions and watchlists and returns back a list of matches. For a list of used watchlists, see Personator Identity Watchlists.
    • Verify: After the data has been checked, identity verification is performed and result codes (KV*) are returned to indicate what pieces of input data have been matched against trusted referenced data.
