# browserAct

> Gateway browser service RPC.

`browserAct` controls a gateway-local ephemeral Chromium session.

* Method: `browserAct`
* Scope: `run:write`
* Transports: HTTP RPC, WebSocket RPC

Request: `{ sessionId, actionId, expectedRevision?, action }`; `action` is a closed union: navigate, history, click, type, press, scroll, or dialog.
Response: `{ revision, page, outcome }`. Replaying `actionId` returns the original outcome.

Text aimed at sensitive fields (password and other masked inputs) is redacted before it reaches the settled action journal, `recentActions`, or the `browser.activity` broadcast. Full `type` actions are masked, and a `press` of a single printable key against a sensitive field masks the key the same way; non-printable keys like Enter stay readable.

Errors are versioned as `v1` and include `InvalidRequest`, `Unauthorized`, `Forbidden`, `REVISION_CONFLICT`, `SSRF_BLOCKED`, `QUOTA_EXCEEDED`, and `Internal`.
