The day each company opened a door to an automated buyer

What this page is229,908 rows held · newest sealed read 2026-10-14

• 27 files appeared on 24 companies between 11 Jun 2026 and 14 Oct 2026. 25 of them, on 22 companies, were still there on our newest read.
• Every one of those 27 rows is a file that was provably not there on a named day and provably there on a named day, out of 229,908 sealed reads of 276 company websites.
• 6 of them were never a 404. on-running.com, dillards.com, bonobos.com, weber.com, arcteryx.com and costco.com answered 200 for /llms.txt the day before as well, with a web page. Only the body tells you which day the real file went up.
• One went the other way. peakdesign.com put a agent-instructions file up on 17 Jul 2026, and it was gone again on 9 Sep 2026. It has answered 404 on every one of the 35 days we have read it since, so this is a file that was taken down, not a read that failed.
• Nobody on the panel served an agent card or either tool-server file on any day. That absence is itself a reading: 276 company websites asked 119 times each, and the count is still zero.

Real rows out of our sealed copies

These are rows we read out of dated copies we keep ourselves. The live source shows today only, so once a row moves, what it said before is gone from the place you would go to look.

What this page cannot tell you

• The thing we observed is that a file appeared at a fixed address. That is not the same as a company launching automated selling, and we never write it as if it were. We cannot tell you whether anything behind the file works, whether a robot can really complete a purchase, or whether the company meant to publish it.
• A server answering 200 is not proof of a file. We count a file as there only when the body we saved really is that kind of file. On 14 Oct 2026 that test threw out 138 answers of 200 across 35 companies whose servers handed back a web page instead.
• On 14 Oct 2026 we could not read one or more files at 87 of the 276 companies, because the server refused us, rate-limited us, timed out, or its robots.txt told us not to fetch. Those are shown as cannot tell. We never count a refusal as the file being gone.
• The panel is a fixed list of 276 company websites, frozen before collection started. A company that is not on that list is not missing from this feed — we have never asked it anything. Email operations@ustechautomations.com with the companies you follow and we will tell you which of them we already hold.
• Our first read is 11 Jun 2026. A file already up that morning shows a first seen date of 11 Jun 2026, and we cannot tell you how long it had been there before we started looking.
• There are 7 days in the window with no read at all: 19 Jun 2026, 4 Jul 2026, 15 Jul 2026, 8 Aug 2026, 18 Aug 2026, 19 Aug 2026, 20 Aug 2026. Where a file appeared across one of those gaps we give the two dates we actually hold, never a guessed one in between.
• We do not report a file as taken down until it has been cleanly absent on every read since, for at least 14 days. A file missing for one read and back the next is our reader having a bad day, not the company changing its mind.
