Quickstart

1.Start with the public endpoint below. No key is required for up to 1,000 requests/day per IP.
2.Add a remote connector in Claude, or save the Cursor configuration shown below. Enable the server’s tools in your client.
3.Ask: "Compare GDP per capita between Vietnam and Indonesia."

Connection

These examples use anonymous access. Clients that support custom headers, including Cursor, can send an X-API-Key header for a larger allowance. Get a key from pricing; keep it out of public configuration files. Claude uses its remote connector setup; Team and Enterprise organizations may require an owner to add the connector first.
