precheckCheck if an AI agent can reach checkout on a store before trying. Saved automated HTTP check for a product or store URL. Uses ARC's saved directory, rails, store answers and check history. When those have no row, uses the plain-HTTP checker. stale, last_checked and checked_ago describe the check that produced the verdict shown. lastReachableCheck is a separate, newer plain-HTTP time. It does not r

find_agent_ready_storesFind stores where a saved check shows an AI agent can reach checkout, for running shoes, beauty, clothing, home goods, or another product need. Reads real HTTP agent-catalog checks from the last thirty days whose catalog found a product and returned a checkout link. This is not a completed order. One tested product is not a promise about another item. No login, browser scan, or model call. Results
params: category, q, limit
can_agent_checkoutCall when you need a saved checkout-link check for any public store URL, not only Index brands. Saved HTTP checkout check for a public homepage or product URL: catalog, product, checkout link, UCP profile, blocks, and one fix. No login, model call, payment, or browser scan. Uses ARC's last check (cached up to 24 hours). A missing result is unknown, not a no. A checkout link means reach checkout, n

ask_arcRead whether an AI agent can reach checkout for a brand the ARC Index already lists. No login and no new scan. Pass a brand, URL, or category.
