api record

Answers where a whole grocery list should be bought today, using real local store prices collected from each retailer's own storefront. Tool calls are x402-paid in USDC on Base — send the base64 X-PAYMENT header on this POST /mcp request (or params._meta['x402/payment']). find_product costs $0.005; price_basket costs $0.01; cheapest_basket costs $0.02 and is the one that answers the whole question, so prefer it over calling find_product per item. An unpaid call returns a PaymentRequired result carrying the x402 accepts challenge and settles nothing; initialize, ping and tools/list are free. Coverage is explicit: an uncovered ZIP or unknown product returns an error and is NOT charged, never a guess. Delivery fees, order minimums and loyalty-card prices are not collected yet and come back null rather than estimated.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • request_data unknown never probed

    FREE, no payment. Describe in your own words the data you are trying to buy — anything, not just groceries — and get back whether we operate a service that supplies it, with the MCP endpoint if so. Every request is catalogued so that repeatedly-requested data gets built; call it whenever you cannot find a source for something. Nothing about you is stored: not your wallet, your address, or any identifying header — only the words of the request.

  • demand_report unknown never probed

    FREE, no payment. The aggregate of what agents have told us they are looking for, most-requested first, with the categories nothing available yet serves. Useful if you are deciding what to build or sell into the agent economy.

  • find_product unknown never probed

    Compare a single grocery item across every collected store in a ZIP. Returns each store's actual current shelf price, whether it is on sale (and the regular price), the package size, the price normalized per comparable unit, stock, a purchase link, and when that price was last read. Use this to answer "who has the cheapest milk near me" — and note the answer reports BOTH the lowest sticker price and the best value per unit, which frequently disagree because the cheap sticker is a smaller package. For a whole shopping list use price_basket or cheapest_basket instead; calling this per item costs more and cannot optimize across stores. Costs $0.005 USDC per call via x402 on Base.

  • price_basket unknown never probed

    Price an entire shopping list at every collected store in a ZIP, one complete basket per store. Returns per-store line items with quantities and line totals, the basket subtotal, exactly which requested items that store is missing, whether the basket is complete, stock flags, and the oldest price in the basket so staleness is visible. Use this when the shopper will make one trip and wants to know where the whole list is cheapest. Accepts quantities as 'milk x2'. Costs $0.01 USDC per call via x402 on Base.

  • cheapest_basket unknown never probed

    The complete buying decision for a shopping list: the cheapest single store that can fill it, AND the cross-store optimum that buys each line wherever it is cheapest, with the dollar savings between them and how many stops that costs. Every line carries substitutes at the other stores with the exact extra cost of choosing them, so a shopper can collapse a two-stop trip into one and see precisely what that convenience costs. Out-of-stock items are skipped in favour of an in-stock option even when it is dearer. Use this as the default for "where should I buy this list today" — it is the one call that answers the whole question. Costs $0.02 USDC per call via x402 on Base.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know
card completeness
90%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
