Questions

Can UCP agents buy from addressfish.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 addressfish.com ready for UCP agents?
addressfish.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?
