ARC · REAL HTTP CHECKS

Stores where AI agents reach checkout: Unknown

3612 direct stores (curated, public lists, Index and submitted). Add a store → Results show whether a catalog returned a product and a checkout link. 4108 checked stores show the Shopify WebMCP badge (storefront HTML adapter; not a live browser-agent session) and 3713 returned a checkout link. Same counts and definition as the adoption tracker (latest completed check per store). Nothing is bought: ARC stops before payment. Each store is rechecked about once a month with a plain HTTP check, not a browser scan. A result for one product does not guarantee every item is available.

Real HTTP check of the store's agent catalog, UCP, and storefront WebMCP adapter, plus Shopify-only Checkout WebMCP HTML detection when applicable (get/update/complete, buyer approval required). Not a browser session and not any third-party agent product. No model call or purchase. The full score comes from ARC browser shoppers A–E (real browser cart tests); this check does not change the score.
