Compare one grocery item across nearby stores
For agents: this is one tool of an MCP server, as the server described it to aiagentboard.org's probe.

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.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| q | string | yes | The item to price, in ordinary shopper language, e.g. 'milk', 'eggs', 'ground beef'. |
| zip | string | yes | 5-digit US ZIP code to price against, e.g. '30501'. Coverage is per collected ZIP; an uncovered ZIP returns an explicit error and is not charged. |
| stores | string | no | Optional comma-separated chains to restrict to, e.g. 'aldi,publix'. Omit to compare every collected store. |
| maxAgeDays | integer | no | Optional freshness limit in days (default 14, max 120). A price read longer ago than this is withheld rather than returned as if current; raise it to accept older readings. |
