toychamp.be doesn't offer AI agents a product catalog yet. Without one, an AI agent has to click through the website like a person.
No agent found a product at this store.
A failed audit caps the grade. "Not measured" is shown as such and never counts as a fail. No payment ever affects a grade.
ARC's automated check got a page back.
ARC's agent did not find a product, and no browser shopper added one to the cart.
Fix: Give agents a product catalog to search (on Shopify, turn on Agentic Storefronts) and publish your products to it.
No checkout link came back from the saved check.
Fix: Make your agent catalog return a cart with a checkout link for the products it lists.
Not measured: no checkout link came back, so there is no route to read.
Not measured in ARC's saved check.
No valid UCP profile: it is missing at /.well-known/ucp or did not pass validation.
Fix: Publish a valid UCP profile at /.well-known/ucp (on Shopify, Agentic Storefronts serves it for you). Generate the fix

What ARC measured at each step, and the evidence for it. ARC stops before payment.

The profile ARC's validator accepts
A catalog an agent can search directly, like Shopify's built-in catalog for agents (UCP MCP)
WebMCP lets a page offer actions, like add to cart, to an AI agent in the browser. ARC looked for it in the page HTML
The agent asks for a cart and gets a checkout URL back
Add a product feed AI agents can read. Publish a product catalog agents can search, using the open Universal Commerce Protocol.

ARC writes these starters from its saved check of toychamp.be. ARC does not change your store and publishes nothing for you. Review each one, replace the placeholders in capitals, and publish only what is true for your store. Each starter is checked by ARC's own validator where one exists.
Starter, review before publishing
ARC found a /.well-known/ucp file that did not pass validation. Compare it with this starter.
A UCP 2026-08-25 skeleton filled in with toychamp.be. The endpoint is a placeholder until you run a UCP service.
Serve as JSON at https://toychamp.be/.well-known/ucp. The endpoint must be a real UCP service you run, and payment handlers depend on your payment provider. Run it through ARC's UCP validator before you publish.

No starter for an agent finds a product; an agent gets a checkout link. Those fixes are a setting or a change ARC can't write as a file; the grade above says what to do.
Starter, review before publishing
An llms.txt gives AI agents a short map of your store. The grade does not check it, so it changes no grade.
