Just wanted to post how impressed I am with the CH API.
Took a few hours to figure out how to call it correctly, and quite a few more to integrate with Google Street View (api restrictions means a couple of server side helper scripts), but traversing the data is a breeze. There are some limits. For example, not having company numbers in legal entities in the PSC (Persons of Significant Control) means one can’t network ownership trees, but still very good. Would love to have VAT numbers since HMRC API only takes those for their queries.
This is a hobby project. Just wanted to see what I could put on a time line. So far: accounts filing, name and address changes, director’s tenure and PSC periods. There is a help page for more info on what it does and how but hoping it is intuitive. Feel free for poke around the code and nab anything of interest. I can’t think of anything else but open to suggestions.
