Which companies let a robot reach their checkout

What this page is20,424 rows held · newest sealed read 2026-08-30

• 68 of the 276 companies served a real checkout manifest at /.well-known/ucp on 30 Aug 2026. This is the file that names a shop's cart, its checkout and the payment methods a robot may use.
• Every one of those 68 manifests names a checkout a robot may drive, and every one names com.google.pay.
• 3 manifests appeared while we were watching and 68 were rewritten after publishing.
• 1 was taken down again and has not come back — the whole reason to hold dated copies rather than trust today's read.

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

• A manifest is a shop saying what a robot may do. We read the file. We do not place an order, do not test the checkout, and cannot tell you whether any of it works.
• 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 30 Aug 2026 that test threw out 157 answers of 200 across 40 companies whose servers handed back a web page instead.
• On 30 Aug 2026 we could not read one or more files at 82 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.
• Most of these manifests are served by the same shop platform, so they look alike. That is what the file says, not a judgement about the company behind it.
• 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.
