Can UCP agents buy from lovelovefrog.store?
Through its REST and MCP services, an agent can search the catalogue, build a cart and start a checkout. The service answered our check. This is what the store declares and what our check reached; an observed agent run shows how far an agent actually gets.
Is lovelovefrog.store ready for UCP agents?
lovelovefrog.store publishes a valid UCP profile and scores 96/100 (grade A). 3 things to fix: 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. lovelovefrog.store's is 2.3 KB, written for UCP 2026-08-25. What goes in a UCP profile.
How was lovelovefrog.store checked?
With public requests on 23 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, and called its REST and MCP service. No sign-in and no purchase. How we check.
