Api Endpoint

blockint.ai

Legacy minimal alias of /screen. Returns result 'caution' (with reportCount, crimeTypes and any OFAC SDN sanctions entries) when reports, an OFAC SDN match or a current Tether/Circle freeze (rated HIGH) are found, otherwise 'no_c3_reports', plus action, actionReason, sanctioned, frozen and freezes. 'no_c3_reports' is not a guarantee that the address is safe.
