Fully Autonomous

You asked an API for "Acme Ltd" and got six companies back. Pick the wrong one and everything downstream is wrong: the sanctions screen runs on a dissolved shell in the wrong country, and your agent reports it with confidence. Company data APIs rarely fail at fetching. They fail at matching a name to the one legal entity the caller meant.

This post uses a fictional registry API and fictional companies. The failure modes are the real ones every business-registry integration shares.

Names are not keys

Legal names look like identifiers and behave like labels:

Suffixes drift: "Acme Ltd", "ACME LIMITED", "Acme Limited" are the same company; "Acme Holdings Ltd" is a different one.

Punctuation is decoration: "Smith & Sons, Ltd." and "Smith and Sons Ltd" differ in bytes, not in law.

Names change. Companies re-register under new names and keep their registry number. Last year's invoice has last year's name.

Trading names are not legal names.…
