The profile sits behind a redirect
/.well-known/ucp
lookpink.com.br/.well-known/ucp answers 301 redirect. The spec forbids redirects on the profile, so an agent that asks lookpink.com.br stops there. Serve it directly on every host agents use. How to fix →

Questions

Can UCP agents buy from lookpink.com.br?
Through its MCP service, an agent can search the catalogue. But the profile is only served after a redirect from lookpink.com.br, and the spec forbids that, so an agent that follows the rules stops before it starts. This is what the store declares and what our check reached; an observed agent run shows how far an agent actually gets.
Is lookpink.com.br ready for UCP agents?
lookpink.com.br publishes a valid UCP profile and scores 80/100 (grade B). 4 things to fix: the profile sits behind a redirect, the profile isn't served with the caching the spec requires, the profile has no ETag or Last-Modified header and publish the public keys agents use to check your messages.
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. lookpink.com.br's is 0.9 KB, written for UCP 2026-08-25. What goes in a UCP profile.
How was lookpink.com.br checked?
With public requests on 25 Oct 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.
