For AI tools

Let Claude and Cursor use our APIs directly.

MCP lets AI tools like Claude, Cursor, and Windsurf talk to our APIs without you writing code. One URL gives your AI tool read-only access to every endpoint.

Free preview, then real use

Try it free, then add a key when you're ready

Without a key, your AI tool can use a list of sample inputs to try things out. Add an API key and it gets the full live data, with the same usage tracking and limits as the regular API.
