Services · read from /.well-known/x402.json

Access the supported feeds and evidence doors.

Start with the public measurements, see their change record and verify the signed evidence. The catalogue below then reads the supported machine doors from the rail's own manifest. Commissioned outputs remain secondary. Verification stays free.

Unread

This copy of the page was rendered without the live manifest. The doors are listed in the machine-readable manifest at /.well-known/x402.json, which this page reads when it loads in a browser. No door is listed here, because listing a door we did not read would be inventing one.

Verification is free and always will be. A grade is never sold, and a measurement is never a certification. Where a door is paid, it is paid at the 402 itself — there is no checkout on this page and no price on this site.
