API Scouting: Document Types

I’m scouting out the Companies House API to see whether it’s the right fit for our project. I have a question about the Document API of which I couldn’t find the answer anywhere in the documentation: what type of documents could I fetch via this method? The main type of importance to us is annual reports, but the more the merrier.

You can fetch every type of document that is available on the filing history for that company.
