Weekly check: Koelnmesse Exhibitors

Every Sunday an automated watchdog runs the live actors on Apify with fixed inputs whose correct answers are known, and checks the content of the results — not only whether the run succeeded. The results are published here as they are, failures included.

First public check on 25 Oct 2026. Until then this page lists what will be checked.

What this shows: on the day of the check, the live actor gave the known answers for these inputs. It does not prove that every result is correct.
