Perceptron DataWeekly check: Free Imprint & Contact Check
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.

Sample against the original source
On 12 Oct 2026 we took 20 result rows and compared 127 field values one by one with the original source: 111 matched (87.4%).
Of the values the actor delivered, 111 of 115 were correct (96.5%); 12 values that the source shows were not delivered.
20 result rows from a local run of the current code on 12 Oct 2026 (large, medium and small companies from Germany, Austria and Switzerland; small ones found via the actor's own OpenStreetMap search). Each field was compared by hand with the legal-notice page the row cites, the VAT verdict with an independent query to the EU VIES service. A field counts when we deliver a value or the source shows one we missed; rows the actor reports as blocked, unreachable or without a legal notice were checked in a browser-like request. After repairs released on 12 Oct 2026 (build 0.1.20), the same 20 rows give 128 of 129 matching fields. These are the rows the repairs were aimed at, so this is not an independent estimate; a fresh sample with new rows follows.

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. The sample against the original source measures accuracy on real result rows.
