Tool

resolvelegalentity

Company domain in, the registered legal entity behind it out.

A null is the product, not a gap

Register search endpoints are fuzzy and they always return something. Taking the top search result gives you a confidently wrong company number more often than not. This actor accepts a match only when the legal names are identical after normalization, which is why roughly 6 domains in 10 resolve instead of 10 in 10, and why the 6 are worth acting on.

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
