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

The rail's manifest at /.well-known/x402.json did not answer (Unexpected token '<', "<!doctype "... is not valid JSON). No doors are listed, because listing a door we could not read would be inventing one. This is not a claim that the rail is down.

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.
