Detected
This is a public file check. It does not mean an agent can buy here. Not found means those files were absent. Not confirmed means ARC could not tell. A missing or unconfirmed result is not a mark against the store.
Checked 2026-10-13 16:26 UTC
Read during the checkout check. ARC stops before payment and does not create an account.
Not recorded yet. ARC reads the page it already opened. It does not type a name, email, or phone number, and it does not submit a signup form.
Not confirmed, and a missing check, are not a mark against the store.
Same measured facts for every assistant. ARC does not test the assistant. Muse is Meta's personal agent, powered by its Muse Wonder models.
No check date is stored yet. A missing line is not a mark against the store.

ASK YOUR AGENT
Check bl4ckb4ll.myshopify.com with ARC's free MCP: https://www.arcreport.ai/api/mcpFree and read-only. The line asks for a saved, dated check. It does not start a new scan.
Install the MCP →Put this free badge on your site. It shows the latest saved result, links back here, and updates after each new check. It says “ARC checkout check passed” only when a measured catalog check returned a checkout link. That is not a completed purchase, and not a live session of a named shopping agent.

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 2026-10-13 16:26 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.
Public checks not fully measured
Not measured items need a successful re-check before readiness can be established.
native_commerce(checkout_eligibility): Can't be checked from outside — set in your Merchant Center feed
These are the public parts of Google's checklist that ARC can check from outside. This is not Google approval or certification. See Google's Merchant Center help on UCP / agentic checkout.
Platform: measured on the next check.
From the product page's JSON-LD, or the store's public products.json when that page has none.
Measured on the next check.
From the store's pages and structured data. Presence does not verify the policy's terms.
Measured on the next check.
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.

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.
