resolve_jurisdictionWhere is this going? Resolve a ship-to (e.g. 'US', 'US-CA', 'UK', 'FR', 'EU-DE', 'JP') to one of the 18 markets and its rule set (13 rule sets; the six EU markets share one). UK is the label; machine fields carry the ISO code GB.
resolve_actorWho is asking? Brand, manufacturer, retailer or distributor (business to business); 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_infor
gate_transactionAllow or deny, with the reason and the rule. Takes a product (GTIN or catalogue id; optional), the ship-to market, the actor class and, when no record exists yet, the product type, ingredients (INCI) and claims. Returns one of twelve reason codes (ALLOW · REQUIRE_NOTIFICATION · R
get_ingredient_recordOne ingredient, and its status in every market: the standard ingredient name (INCI), aliases, and per rule set whether it is prohibited, restricted (with the limit or condition) or listed, each with the official list and its source page.
get_market_statusIs this product type a cosmetic here? Product type by market: cosmetic, drug, special class (functional cosmetic, quasi-drug, grade 2, therapeutic good) 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 notification scheme, the responsible-person requirement and, for a product type in a special class, the extra step (review, registration, listing) — each with its source page.
get_label_and_claimsWhat the label must say, and which claims are allowed: the label requirements of the market and the claims rules of record (patterns that take a product out of the cosmetic class), each with its source page. Optional claims are checked against the rules.
get_enforcement_watchRecalls, bans and safety alerts, dated: enforcement events by market, ingredient, brand or since a date, each with its source page.
search_cleared_itemsFind products cleared for this market: validated product records in a market (query by product name, brand, product type or lane; optional lane filter: suncare · fragrance · dermocosmetics · peptides · korean · sustainable). Only validated rows are served; each item carries its c
get_itemProduct record from gtinfetch.ai (signed); hub layer: seat, market, claim, price, availability. One product by GTIN, fully resolved: taxonomy path, variant or form, brand, market, claim status, market status, availability; after the gate also ingredients, claims, attributes, shad
compare_itemsCompare products, variants and shades side by side (two to eight GTINs or catalogue ids).
find_verified_supplierVerified makers and brands for this product or product type in a market: supplier records (brand · manufacturer) with their claim status — verified first, then claimed, then listed. Takes the decision_id of an allow decision.
get_availabilityIn stock, and where: the availability block of a product (banners on the shelf of record, product URLs read live at load, store counts where the retailer record carries one) once gate_transaction has answered allow (decision_id).
get_priceThe price for this buyer: the price basis (list · contract) from the supplier's offers on the record, once gate_transaction has answered allow (decision_id). Tiers buy services, never rank.
get_product_documentsSafety report, certificate of analysis, data sheet: the documents on a product record (product information file pointer, safety assessment, certificate of analysis, safety data sheet), each a URL with its read date; decision_id required.
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 and claim status.
create_order_intentOpen an order between two agents: an order intent for a cleared product 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 (the regulator's home page beside it) — a referral, never a sale to a consumer
claim_seatA brand's agent claims its seat on A2A Cosmetics. 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 (beauty and personal care proceed; a grocery record is referred to a2a-gro
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

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_safety_labelWarnings and age limits: the warning statements the market requires for a product type (sunscreen, hair dye, aerosols, children's products) and the safety-alert scheme of the regulator, each with its source page.
log_auditWrite a line to the audit record for a gate decision, an order intent or a handoff (returns the line id).

Agent-to-Agent (A2A) + Model Context Protocol (MCP) hub for cosmetics.
Business to business: brands, manufacturers, retailers, distributors and their AI agents. Eighteen markets, thirteen rule sets; every answer names the market, the rule set and the version it was judged against. Operated by GreenCore Solutions Corp. Public connect kit, MIT.
Notice: Artificial intelligence makes mistakes. A2A Cosmetics is an information source, not a recommendation. Rules differ by jurisdiction — refer to the regulator in your jurisdiction for the information that applies to you.
