How the score is made

three areas, weighted
Discovery 30%
Can a UCP agent find and read the profile: HTTPS, an answer at /.well-known/ucp, robots.txt allowing it, and five files outside UCP (llms.txt, sitemap, Open Graph, Organization schema, viewport).
95−1.5 pts
Conformance 40%
Does the profile follow the spec: valid against its release (counted three times), a dated release, keys published, few warnings, spec and schema links that resolve.
97−1.2 pts
Capabilities 30%
What an agent can do here: how many capabilities, checkout, at least one service, payment handlers, and services that answer our check.

1Publish Organization schema (JSON-LD) on the homepage
No Organization-typed JSON-LD detected on your homepage.
Organization schema gives agents a structured representation of your brand identity: name, logo, social profiles, contact info, founding date. Agents use this to verify you are who you claim to be and to link your profile data to a recognizable entity.
