- `get_company`: Get the public registry record of one Singapore entity by its UEN: name, entity type, status and status date, incorporation date, SSIC activities, registered address (when shown publicly), conversion successor, SGPID and its sgpbusiness.com profile link, plus the open-data attribution to include when presenting it.
