Guides
What exists, what it does, and what to ask
Surveys of the tools available for financial computation — calculator APIs, vendors serving banks and credit unions, finance MCP servers, and eval datasets — with every named product traced to the registry or page it was read from, and the date it was checked.
We sell one of the things described in most of these, and each guide says where that shows.
