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.
96−1.6 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.

1Make declared services answer with UCP
One or more declared service endpoints did not give a UCP answer when probed.
A declared endpoint that does not answer stops an agent at that step, even though the profile itself validates. Connection refused, DNS failure, TLS errors, and 5xx responses all fall here. See the Full Check Breakdown below for the specific endpoints that failed.

Conformance · effort low
2Fix broken spec or schema URLs
One or more spec/schema URLs declared in the profile do not resolve.
Spec and schema URLs let agents validate request/response shapes before sending. When they 404 or time out, runtime validation degrades to "best effort" and strict agents reject the integration entirely. Common cause: copy-pasting a placeholder URL during initial profile setup. See the Full Check Breakdown for the specific URLs that failed.

3Publish 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.
<script type="application/ld+json">
{
"@context": "https://schema.org",
"@type": "OnlineStore",
"name": "Yourstore",
"url": "https://yourstore.com",
"logo": "https://yourstore.com/logo.png",
"sameAs": [
"https://twitter.com/yourstore",
"https://www.instagram.com/yourstore"
],
"contactPoint": {
"@type": "ContactPoint",
"telephone": "+1-800-000-0000",
"contactType": "Customer Service"
}
}
</script>
Drop into <head> or end of <body>. Use OnlineStore (more specific) when the entire site is an ecommerce store; Organization is the generic fallback.
