Observability

Poll ordered V4 events to monitor a run or build a custom UI.

Poll runs.events() with the previous cursor to receive only new events:

Python

import time

after = None
while True:
    page = client.runs.events(run.id, after=after)
    for event in page.events:
        print(event.type, event.data)
    after = page.next_after if page.next_after is not None else after

    status = client.runs.status(run.id).status.value
    if status in {"completed", "failed", "cancelled"}:
        break
    time.sleep(1)

Events cover run lifecycle, model calls, browser readiness, tool activity, artifacts, and completion. See Get run events for the complete response shape.

For browser HTTP traffic, attach your own CDP network observer. Run events are not a network log or a historical HAR export.
