Request

{
  "input": {
    "scheme": { "type": "ofac:sdn", "value": "12345" }
  },
  "subject_source": "ofac_sdn",
  "match_op": "equals",
  "reference_id": "kyc-2026-05-001"
}
FieldRequiredNotes
input.schemeyes{type, value}. type is the scheme namespace, e.g. br:cnpj.
subject_sourcenoPin lookup to a single source. Omit to search all available.
match_opnoequals (default, exact canonical match) or ilike (% wildcards).
reference_idnoCaller-provided correlation id, echoed in response.
The identifier value is canonicalized server-side: spaces, dashes, dots, slashes, and parentheses are stripped, case is normalized. So "12.345.678/0001-90" and "12345678000190" are equivalent.

Response

{
  "data": {
    "matches": [
      {
        "source_name": "ofac:sdn",
        "source_id": "sdn-12345",
        "value": "12345",
        "indexed_at": "2026-04-30T00:00:00Z",
        "properties": { "name": "...", "program": "..." }
      }
    ],
    "subject_check": "ok",
    "reference_id": "kyc-2026-05-001"
  },
  "meta": { "request_id": "..." },
  "errors": []
}
An empty matches array means no match was found. subject_check is "ok" when all sources answered, "failed" when a partial answer was returned.
