Local API

The desktop app's background service listens on http://127.0.0.1:27100 (change it with ANT0D_PORT). Every request needs the bearer token shown in Desktop → Automation; the command line reads it for you. Starting a profile returns a session whose ws_endpoint Playwright or Puppeteer can connect to over CDP.

Note

The API only answers on your own computer, so this page documents it without sending requests. Try calls with curl or the ant0 command. Download openapi.json
