Resolve a company by an external identifier. Exact match, not fuzzy name search. POST /v1/entities/lookup accepts exactly one of these identifier schemes:
  • Takes one identifier scheme and value
  • Returns a single entity stub (id, name, entity_type, description)
  • Use the returned id with Retrieve Entity / Entity Introspection for a full profile

Example:

Or as a top-level shorthand:

Lookup result

One matching entity stub. Feed the id into Retrieve Entity for properties, relationships, and numerical observations.
Lookup is exact: the identifier must match the value stored in the Knowledge Graph (whitespace is stripped; LEI is uppercased; CIK is zero-padded to 10 digits).
Unknown identifiers return 404. Unknown schemes return 422.
