The profile has no ETag or Last-Modified header
Spec level: SHOULD.
To fix
Your store lives on www.davona.cz; davona.cz only redirects to it
How we decided: davona.cz forwards its homepage to www.davona.cz; your homepage names www.davona.cz as its canonical address; and your UCP profile is served directly at www.davona.cz/.well-known/ucp. An agent given davona.cz instead gets a redirect, and the spec tells agents not to follow one, so it stops there. Serve /.well-known/ucp directly on davona.cz too if agents may use it.

Questions

Can UCP agents buy from davona.cz?
Through its REST service, an agent can search the catalogue, build a cart and start a checkout. This is what the store declares and what our check reached; an observed agent run shows how far an agent actually gets.
Is davona.cz ready for UCP agents?
davona.cz publishes a valid UCP profile and scores 90/100 (grade A). 3 things to fix: the profile has no ETag or Last-Modified header, cryptographic message signing is not yet enabled and your store lives on www.davona.cz; davona.cz only redirects to it.
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. davona.cz's is 1.5 KB, written for UCP 2026-08-25. What goes in a UCP profile.
How was davona.cz checked?
With public requests on 4 Nov 2026: we read /.well-known/ucp and robots.txt, validated the profile against UCP 2026-08-25, checked that its spec and schema links resolve. No sign-in and no purchase. How we check.
