Connect Cursor to OpenStreetMap
One line gives Cursor your OpenStreetMap account as tools: 13 endpoints, notes, traces, map data, called with your own connection. No key in the prompt, a receipt for every call, revoke Cursor's access alone any time.
Three steps
- Create a free 0n3 account and connect OpenStreetMap. Paste a key or sign in; it lands in your vault, encrypted.
- Install 0n3 into Cursor. Click one button and Cursor adds 0n3.
- Ask Cursor: whoami. Then: "Search notes in OpenStreetMap".
Click the button. Cursor opens and adds 0n3.
The line above carries a placeholder; 0n3.app/install mints a real key named for Cursor and fills it in.
