Read the session’s debug resource to obtain its current live-view and page-selecting debugger URLs. Do not construct a URL from a website path.
curl "https://api.tooluse.net/v1/browsers/sessions/$SESSION_ID/debug" \
-H "Authorization: Bearer $TOOLUSE_API_KEY"
Keep these URLs private. They grant access to a browser page and may expose signed-in content. Their availability depends on a running session and the selected transport. A closed or expired session is not restored by opening an old URL.
For an end-user sign-in or human check, create an explicit handoff and follow its completion state before resuming automation. Do not infer completion from an undocumented iframe event.
