Without one, an AI agent has to click through the website like a person.
Checked yesterday. Based on ARC's automated checks, not a live agent session. How we check
Can AI agents find your products? No.
No. Your site doesn't offer AI agents a product catalog they can search.
Can they read prices and stock? Not tested yet.
Not tested. We couldn't open a product page on your site to check.
Can they get to checkout? No.
No. Without a product catalog to search, our agent had no way to reach checkout.

Turn on Shopify's catalog for AI agents
Shopify can let AI agents search your products and build a cart. Make sure it's on for your store.

Agent Reachability Matrix
Existing ARC evidence shows discovery rails, checkout paths, and known block risks. A detected rail is not a promise that a named agent can use it.

Rail / discovery evidence checked 2026-10-10 19:41 UTC. Index cart evidence uses the published scan below.
Measured means an ARC HTTP rail check or an Index browser cart test, not a live Muse, Instinct, ChatGPT, Gemini, Grok, or OpenClaw session. Checkout handoff is not a completed purchase. ARC is independent and not affiliated with Meta, Sierra, Shopify, OpenAI, or Google. PAP support is not confirmed.
Real HTTP agent-catalog check. Does not change the Index score.
No agent catalog found in this check.

The fix
Expose a catalog agents can query over HTTP. On Shopify, enable search_catalog or search_shop_catalog at /api/ucp/mcp or /api/mcp and publish the /.well-known/ucp profile.
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.
Public checks need attention
Not measured items need a successful re-check before readiness can be established.

https://linksys.com/PAP (announced Oct 2026 by Meta and Sierra with industry partners) is an open standard for how personal agents discover and work with businesses — website discovery, OAuth session, then site / APIs (MCP, OpenAPI) / company agent. ARC already answers the two-lane question: can agents discover you, and can they buy from you. Until the v0.1 spec ships, we probe sensible discovery candidates and label unknown clearly. ARC is not affiliated with Meta or Sierra.
Watching for PAP v0.1
No PAP-specific discovery markers detected yet. Spec v0.1 is not published; ARC is watching, not inventing support.
Not a claim of PAP support. Spec v0.1 is expected later this month; reference implementation coming. Related surfaces below (UCP, WebMCP, MCP well-known) are existing agent-discovery checks — not PAP.

Browser cart attempts. Score is this lane only.
Not on the curated Index yet. You can still run a free product scan.
Typed decisions over an HTTP product scrape. Not a live personal-agent session.
No Jev facts stored yet for this host.
Quoted mismatches only, from one AI model’s read-back (currently Grok via API). One model, not a consensus.
No real Grok fact check stored for this store yet.
From stored ARC rows only.
Claims never change ARC’s measured scores.
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.
