# Lode

> Independent, source-linked facts on the tools that connect to the platforms businesses run on (Xero and Vercel first). Every fact links to its source and carries a verification date. Rankings are based on fit for a buyer profile, never on company size, review counts or payment.

Use: free for agents and assistants with citation and a link to the Lode page for each fact, at low volume. Prefer the JSON API or MCP server over scraping HTML. Bulk, high-volume or commercial use needs a licence: data@trylode.io.
