ARC INDEX · WEEKLY
Where can personal agents reach checkout?
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. Each store has two lanes. A real HTTP check asks the agent catalog for the product and a checkout link. Five browser cart shoppers try the page. The score is the browser lane. The catalog check does not change it. Checkout on this table is the real link, yes or no.
One shopper at a time: Shopper A, Shopper B, Shopper C, Shopper D, Shopper E. What agents get wrong · State of agent checkout.
Latest test in this view: 6 Oct 2026. Scores appear as each test finishes. How ARC tests
83 of 89 stores in this view have a published score. 6 have no retest scheduled. Nothing here is estimated.
What Grok tells shoppers is a real model call via API, checked against the store's pages, not the consumer Grok app. Whether agents reach checkout is two lanes: a real HTTP check of the store's agent catalog, and five ARC browser cart tests. Those attempts are not a live Muse, Instinct, Grok Bot, OpenAI dots, or OpenClaw session. The score is the browser lane. The catalog check does not change it.
7 of 83 scored stores in this view. Rank stays the score rank. No agent catalog means the check found no catalog tool and no valid UCP profile.

Checkout is the real agent-catalog link. Browser is the browser cart. Is this your store? Claim your page with a free scan.

A test already ran and ARC could not stand behind it. No further retest is scheduled this week. That is not a brand failure, and it is not ranked.
A brand can ask for a re-test or to be removed. Contact ARC or email hello@arcreport.ai.
