Tools
| Tool | Description | Behaviour |
|---|---|---|
| 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 (the regulator's home page beside it) — a referral, never a sale to a consumer. | Changes data |
| claim_seat | A 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-grocery.ai; peptides to a2a-peptides.ai; beer, wine and spirits are refused; an unresolved GTIN is refused). An accepted claim answers a challenge for the card's domain (a DNS TXT record or a well-known file); call again with the challenge_id once it is published: a pass moves the brand's rows from listed to claimed and answers the seat key. With the seat key, rows sets the seat's own price, availability, markets and claims, its own GTINs only. Every claim, accepted or refused, is logged. Verified is a person's step, never a tool's. | Changes data |
| compare_items | Compare products, variants and shades side by side (two to eight GTINs or catalogue ids). | Read-only |
| create_order_intent | Open 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. | Changes data |
| find_verified_supplier | Verified 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. | Read-only |
| gate_transaction | Allow 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 · REQUIRE_RESPONSIBLE_PERSON · DENY_NOT_A_COSMETIC_HERE · DENY_INGREDIENT_BANNED · DENY_INGREDIENT_LIMIT · DENY_CLAIM · DENY_MARKET · DENY_ACTOR_CLASS · DENY_UNLICENSED_AGENT · DENY_NO_GTIN · DENY_NOT_VERIFIED), the rule-set version, the source page and a decision_id for the downstream tools. | Read-only |
| get_availability | In 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). | Read-only |
| get_enforcement_watch | Recalls, bans and safety alerts, dated: enforcement events by market, ingredient, brand or since a date, each with its source page. | Read-only |
| get_ingredient_record | One 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. | Read-only |
| get_item | Product 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, shades (parent and child) and offers. | Read-only |
| get_label_and_claims | What 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. | Read-only |
| get_market_status | Is 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. | Read-only |
| get_notification_requirements | What 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. | Read-only |
| get_price | The 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. | Read-only |
| get_product | Universal 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 <market>:<gtin14>; context; filters}. One product of the priced subset with its variants per market, list price and claim_status; outside the subset, ucp.status error and not_found. | Read-only |
| get_product_documents | Safety 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. | Read-only |
| get_safety_label | Warnings 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. | Read-only |
| log_audit | Write a line to the audit record for a gate decision, an order intent or a handoff (returns the line id). | Changes data |
| lookup_catalog | Universal 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 (<market>:<gtin14>), up to 50; context; filters}. Found rows come back as products with their claim_status; an id outside the priced subset answers an info not_found message. | Read-only |
| resolve_actor | Who 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_information or public. | Read-only |
| resolve_jurisdiction | Where 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. | Read-only |
| search_catalog | Universal 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, cursor}}. Serves the priced subset: rows whose maker's list price is on the record (claimed seats with a listed price), keyed by GTIN, each with its claim_status. Every other row stays on search_cleared_items. | Read-only |
| search_cleared_items | Find 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 claim status and market status. | Read-only |
| 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 and claim status. | Read-only |
