State of agent checkout
The open benchmark of whether AI agents can reach checkout, for every store, agent and protocol. Free, neutral and open: dated checks of whether agents can reach a store, read its products and get to checkout, across every protocol. The data is CC-BY. This page counts the real HTTP check: can an agent query the catalog, find the product, and get a checkout link?
89 of 89 Index stores have a finished check, from 6 Oct 2026 to 11 Oct 2026. Latest check 11 Oct 2026. Failed checks (0) are not treated as no catalog. Unchecked stores: 0.

BROWSER LANE, BESIDE THE REAL CHECK
Of 65 stores with a checkout link and a published browser score, 15 are 0 of 5 on the browser lane, including 9 whose browser stop is the cart.
Of 7 stores with no usable rails and a published browser score, 3 are 0 of 5 in the browser too. The score is that browser lane. This page does not change it. A checkout link and a stuck browser shopper are different facts.
No usable agent catalog
These finished checks found no catalog tool and no valid Universal Commerce Protocol profile. The free HTTP check also detects the Shopify WebMCP adapter in storefront HTML; this is not a live browser-agent session.
