kongcompany.com publishes a valid UCP profile and scores 90/100 (grade A). 6 things to fix: the profile has no ETag or Last-Modified header, repair declared transport endpoints, move to the latest UCP protocol version and publish a /llms.txt brand brief.
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. kongcompany.com's is 2.6 KB, written for UCP 2026-04-08. What goes in a UCP profile.
How was kongcompany.com checked?
With public requests on 17 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.
