이 세 가지는 절대 하나의 점수로 합치지 않아요. 의견, 측정, 인기는 서로 다른 것이니까요.
이 서버는 아직 쉬운 말로 된 요약을 쓰지 못했어요. 아래는 레지스트리에서 읽어 온 사실이에요.

resolve_jurisdictionWhere is this going? Resolve a ship-to (e.g. 'DE', 'US-CA', 'UK', 'FR', 'EU-NL', 'JP') to one of the 20 markets and its rule set (14 rule sets; the seven EU markets share one food-law set with national riders). UK is the label; machine fields carry the ISO code GB.
resolve_actorWho is asking? Maker, brand owner, private label, distributor, importer, broker or retail buyer (trade only); auditor (read-only); agent (inherits the class of the credential it presents — none returns DENY_UNLICENSED_AGENT). The consumer is never the counterparty. Returns commun
gate_transactionAllow or deny, with the reason and the rule. Takes an item (GTIN or catalogue id; optional), the ship-to market, the actor class and, when no record exists yet, the product type, ingredients and claims. Returns one of twelve reason codes (ALLOW · REQUIRE_NOTIFICATION · REQUIRE_RE
search_cleared_itemsFind items cleared for this market: validated SKU records in a market (query by product name, brand, maker or category; filters: temperature ambient · chilled · frozen · fresh, attribute lane organic · free-from · plant-based · artisan · origin · premium, department). Only valida
get_itemProduct record from gtinfetch.ai (signed); hub layer: seat, market, claim, price, availability. One item by GTIN (EAN in European copy), fully resolved: temperature, department → super category → category, attribute lanes, pack, brand and maker, market, claim status, market statu
verify_gtinProduct record from gtinfetch.ai (signed); hub layer: seat, market, claim, price, availability. Is this GTIN real, and whose is it? Check-digit validation, the GS1 prefix, and the validated record(s) that carry it on this hub with their brand, maker and claim status.
get_label_and_claimsWhat the label must say, and which claims are allowed: the labelling requirements of the market (food information, allergens, origin, nutrition) and the claims rules of record (nutrition and health claims, organic, free-from), each with its source page. Optional claims are checke
compare_itemsCompare items, variants and pack sizes side by side (two to eight GTINs or catalogue ids).
find_verified_buyerRetail buyer desks for this market: banner records (banner, parent group, channel discounter · e-commerce · local · in-store · traditional, local format, cited POS count or NULL, buyer desk by department) with their claim status — verified first, then claimed, then listed. Filter
find_verified_supplierVerified makers, brand owners, private-label owners, distributors and importers for this item or category in a market: maker records with their claim status — verified first, then claimed, then listed. Takes the decision_id of an allow decision.
get_product_documentsCertificates and paper: the documents on an item record (organic certificate, PDO/PGI, halal, kosher, specification, allergen statement, origin declaration, lot where it applies), each a URL with its read date and source class; decision_id required.
log_auditWrite a line to the audit record for a gate decision, an order intent or a handoff (returns the line id).
get_priceThe price for this buyer: the price basis (list · contract · promotion window) from the maker's offers on the record, once gate_transaction has answered allow (decision_id). Plain $ on human surfaces. Tiers buy services, never rank.
get_availabilityIn stock, and where: the availability block of an item (banners on the shelf of record, product URLs read live at load, POS counts where the banner record carries a cited one) once gate_transaction has answered allow (decision_id).
create_order_intentOpen an order between two agents: an order intent for a cleared item after the gate; the intent carries reason_code + rule_set_version and settles by x402 on a2a-x402.ai.
a2a_handoffHand the buyer to the right agent over Agent-to-Agent (A2A): with an allow decision the order intent goes to the counterparty's agent (envelope + card URL); with a deny, the market agent of the ship-to — a referral, never a sale to a consumer.
claim_seatA brand's agent claims its seat on A2A Grocery. Give the agent's card URL and the GTINs the brand claims: every GTIN must resolve on gtinfetch.ai to the maker the card names, and the category comes first (grocery proceeds; a beauty record is referred to a2a-cosmetics.ai; peptides
search_catalogUniversal Commerce Protocol (UCP) catalogue search, version 2026-08-25 (dev.ucp.shopping.catalog.search). arguments: meta {'ucp-agent': {profile}} (required) and catalog {query, context {address_country}, filters {categories, price {min, max} in minor units}, pagination {limit, c
lookup_catalogUniversal Commerce Protocol (UCP) catalogue lookup, version 2026-08-25 (dev.ucp.shopping.catalog.lookup). arguments: meta {'ucp-agent': {profile}} (required) and catalog {ids: product ids (GTIN) or variant ids ( : ), up to 50; context; filters}. Found rows come back as products w
get_productUniversal Commerce Protocol (UCP) product detail, version 2026-08-25 (dev.ucp.shopping.catalog.lookup). arguments: meta {'ucp-agent': {profile}} (required) and catalog {id: a GTIN or a variant id : ; context; filters}. One product of the priced subset with its variants per market
get_market_statusIs this product type a food here, and under which regime? Product type by market: food, special class (novel food, food supplement, infant formula, fortified, organic-certified, alcohol excise) or not permitted — with the rule-set version and the regulator's page.
get_notification_requirementsWhat must be filed before sale in a market: the food business registration or import notification scheme, the food business operator of record, and, for a product type in a special class, the extra step (novel-food authorisation, organic certification, supplement notification) —
get_enforcement_watchRecalls, withdrawals and food-safety alerts, dated: enforcement events by market, category, brand or since a date, each with its source page.

Powered by SCHEMA algo for grocery agentic commerce
Agent-to-Agent (A2A) + Model Context Protocol (MCP) hub for retail grocery. Business to business: makers, brand owners, private label, distributors, importers, retailers and their AI agents. Twenty markets on the SCHEMA algo grocery record; ambient, chilled, frozen and fresh; organic, free-from, plant-based, artisan, origin and premium lanes. Call resolve_jurisdiction, then resolve_actor, then gate_transaction before any availability, price, documents, order or handoff tool; those tools refuse without an allow decision. Every record field carries its source page; every response carries notice; every record carries claim_status (listed · claimed · verified). Artificial intelligence makes mistakes. A2A Grocery is an agentic information source, not a recommendation. No ads, ever. No rank for sale. Trade only.
A2A Grocery is built and run by GreenCore Solutions Corp. (github.com/greencore-solutions). This is the public connect kit, MIT.
