resolve_jurisdiction | Where 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. params: ship_to* |
resolve_actor | Who 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 communication_class: trade_information or public. params: actor_class*, credential |
gate_transaction | Allow 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_RESPONSIBLE_PERSON · DENY_NOT_PERMITTED_HERE · DENY_INGREDIENT_BANNED · DENY_INGREDIENT_LIMIT · DENY_CLAIM · DENY_MARKET · params: ship_to*, actor_class*, product, product_type, ingredients, claims, channel, credential |
search_cleared_items | Find 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 validated rows are served; each item carries its claim status, market status and source class. params: market*, query, temperature, lane, department, product_type, limit, decision_id |
get_item | Product 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 status, availability; after the gate also ingredients, allergens, claims, origin, certificates, variants and offers. params: gtin*, market, decision_id |
verify_gtin | Product 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. params: gtin* |
get_label_and_claims | What 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 checked against the rules. params: market*, claims, product_type |
compare_items | Compare items, variants and pack sizes side by side (two to eight GTINs or catalogue ids). params: gtins*, market, decision_id |
find_verified_buyer | Retail 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. Filters: channel, department. Takes the decision_id of an allow decision. params: market*, decision_id*, channel, department, query, limit |
find_verified_supplier | Verified 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. params: market*, decision_id*, gtin, query, lane, limit |
get_product_documents | Certificates 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. params: gtin*, decision_id*, market |
log_audit | Write a line to the audit record for a gate decision, an order intent or a handoff (returns the line id). params: kind*, reference_id*, note |
get_price | The 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. params: gtin*, decision_id*, market |
get_availability | In 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). params: gtin*, decision_id*, market |
create_order_intent | Open 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. params: gtin*, quantity*, decision_id*, market, ship_to |
a2a_handoff | Hand 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. params: intent_id, decision_id, counterparty_card_url |
get_market_status | Is 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. params: product_type*, market* |
get_notification_requirements | What 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) — each with its source page. params: market*, product_type |
get_enforcement_watch | Recalls, withdrawals and food-safety alerts, dated: enforcement events by market, category, brand or since a date, each with its source page. params: market, query, since |
