In the dashboard
Telemetry → Sessions in the dashboard, pick a running session. You can scroll, click and type in it. The Workbench has the same view next to a script editor for trying options before writing code.From a viewer URL
cdpUrl in as is, no encoding; the viewer reads everything after ws=. Print the URL as soon as the session exists so the person has time to open it. It shows the tab your script is driving.
Anyone with the URL can drive the browser; treat it like the API key. It stops working when the session ends.
The session record
After a session ends its dashboard page keeps: status and duration, bandwidth and cost, node and country, how it was started (type, profile, note, API key), timestamps. Log thesessionId so you can find a run later.
The API keeps the essentials: GET /v1/browser/session has status, stoppedAt and bandwidthBytes; the list adds type and country. Cost, network and node details are dashboard-only.
