FOR AGENTS

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.

Read the Index with no login. Everything is free.

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.

Brands use Your store; agents keep MCP free

Brand owners: open /store — paste a URL, no login. Free store page shows whether agents can reach you, buy, and what they think. Agents: keep using the free JSON and MCP tools below.

Free agent facts for any store

Brands get free truth. Agents get free fuel. Call get_agent_facts or list_category_agent_facts on /api/ask. JSON: GET /api/agent-facts?host=allbirds.com or ?category=beauty&download=1.

Facts are TypeSafe Jev typed decisions over an HTTP product scrape — not a browser session and not any third-party agent product. Browser cart results come from ARC browser shoppers A–E.

{"name":"get_agent_facts","arguments":{"host":"allbirds.com"}}
{"name":"list_category_agent_facts","arguments":{"category":"beauty","limit":10}}

Can an AI agent check out from any store?

Find stores where an AI agent can reach checkout: call find_agent_ready_stores on /api/ask with {"category":"running shoes","limit":10}. JSON: GET /api/agent-checkout/stores?category=footwear. Only real HTTP checkout-positive checks from the last seven days are returned. One tested product; no purchase completed.

Browse stores by category →

Free, no login: call can_agent_checkout on /api/ask with a public homepage or product URL. JSON: GET /api/agent-checkout?url=. Scans and monitoring on /api/mcp require OAuth.

GET https://www.arcreport.ai/api/agent-checkout?url=https://allbirds.com
{"name":"can_agent_checkout","arguments":{"url":"https://allbirds.com"}}

Returns catalog, product, checkout-link, UCP, Shopify WebMCP adapter detection (webmcp), Shopify-only checkout HTML detection (checkoutWebmcp: status, nullable detected, tools, reason; buyer approval required), and block facts, a fix, and a shareable result URL. Cached per host for 24 hours. Limits per network per UTC day: 50 requests and 10 fresh checks. Site-wide: 5,000 requests and 500 fresh checks. No order is placed. No score changes.

Ask with a URL

Pass a brand, a product URL, or a category. You get whether agents can reach checkout, the score, rivals Grok named when a real read exists, and the evidence receipts. A missing score is not a zero. This does not start a scan.

GET https://www.arcreport.ai/api/ask?q=running+shoes
GET https://www.arcreport.ai/api/ask?url=https://www.allbirds.com
GET https://www.arcreport.ai/api/ask?brand=Gymshark

MCP, no login: point the client at https://www.arcreport.ai/api/ask and call ask_arc. The signed-in server at /mcp is the one that runs a new scan.

Machine-readable: OpenAPI for this ask API. MCP clients can discover both servers at /.well-known/mcp.json and /.well-known/ai-catalog.json. ask_arc, can_agent_checkout, and find_agent_ready_stores need no login. Scans and monitoring require sign-in.

agents_can_buy
True when the agent catalog returned a checkout link, or a browser cart shopper added the product. False when both lanes are known and neither finished. Null when neither lane has a result.
buy
Both lanes. agent_catalog is the real HTTP check (status, checkout_link, catalog_found). browser is the browser cart count and where it stopped. verdict is the sentence that uses both.
score
The published ARC score from the ARC browser cart. The agent-catalog check does not change it, so older scores stay comparable. Null when no test is published.
agent_rails
The same real HTTP check as buy.agent_catalog, kept for readers that already use this field. Null until a catalog check is stored. Not a Muse, Instinct, Grok Bot, dots, or OpenClaw session.
rivals_grok_named
Names from a real Grok read. Empty when that read does not exist or did not name a rival.
evidence
Receipts: what Grok said, what the store page says, and the quote. Empty when the read is pending re-check.

Categories you can cite

Ranked by score, then by how many agents added the product to the cart. Shopper words like running shoes and leggings map to these.

A store on the Index can embed this image. It links back to that store's ARC page. It says Agent checkout when the real catalog check returned a checkout link, and Agents chose us only when a browser cart shopper added the product to the cart.
