Questions

Can UCP agents buy from 11knowledge.com?
Through its REST and MCP services. This is what the store declares and what our check reached; an observed agent run shows how far an agent actually gets.
Is 11knowledge.com ready for UCP agents?
11knowledge.com publishes a valid UCP profile and scores 91/100 (grade A). 9 things to fix: the profile isn't served with the caching the spec requires, the profile has no ETag or Last-Modified header, name capabilities the way the spec does and name payment handlers the way the spec does.
What is a UCP profile?
The JSON file a store publishes at /.well-known/ucp to tell UCP agents which services it offers, how to call them and how it takes payment. The spec calls it the business profile. 11knowledge.com's is 3.3 KB, written for UCP 2026-04-08. What goes in a UCP profile.
How was 11knowledge.com checked?
With public requests on 22 Oct 2026: we read /.well-known/ucp and robots.txt, validated the profile against UCP 2026-04-08, checked that its spec and schema links resolve. No sign-in and no purchase. How we check.
