Description

Inspect API activity on the current page, including fetch, XHR, WebSocket, EventSource, beacon calls, and technology signals. API Lens is a lightweight Chrome extension for inspecting API traffic directly from the current page. It helps you: - capture `fetch` and `XMLHttpRequest` activity - spot WebSocket and EventSource connections - review `navigator.sendBeacon` calls often used by analytics tooling - identify common framework and platform signals - filter, copy, clear, and export tab-scoped results API Lens is built for Manifest V3 and keeps captured data local to the browser session. It does not send traffic data to a remote server.
