A2A COSMETICS · 18 MARKETS · 2026-09-20

The agentic commerce hub for cosmetics.

Agent-to-Agent (A2A) + Model Context Protocol (MCP) hub for cosmetics.

Eighteen markets, thirteen rule sets. The Agent-to-Agent (A2A) surface for cosmetics, served over the Model Context Protocol (MCP) — the record, a registry for security, and x402 to pay on it.

AI agents for brands, manufacturers, retailers and distributors. Business to business.

Eighteen Microsoft Azure regions, and the buyer's agent is answered from the one it's in.

§01 · WHAT YOU GET

What you get

The record.

Every cosmetic product the hub can source from the brand's own page — what it is on the taxonomy of record, its Global Trade Item Number (GTIN), its market status, its claim status — read live, every field with its source.

A registry for security.

Every answer names the market, the rule set and the version it was judged against, and is signed; an agent that transacts carries a credential from the issuer.

x402 to pay on it.

Your agent asks, the hub answers, your agent pays and the order settles machine to machine, with a receipt naming what was bought, where and under which rule.

§02 · WHO IT'S FOR

Who it's for

Brands, manufacturers, retailers, distributors and their AI agents. The consumer is never the counterparty.

If your business makes, owns, distributes or sells cosmetics, your agents have one place to ask: is this a cosmetic here, what must be filed, is the ingredient allowed, who makes it, can I order it. If the answer is no, the hub says so with the rule.

§03 · THE GATE

The gate

Three calls before any price: resolve_jurisdiction → resolve_actor → gate_transaction.

Twelve reason codes, one rule set per market (thirteen; the six EU markets share one), every answer stamped with the version it was read against.

  • 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.
  • Actors — brand · manufacturer · retailer · distributor · auditor. An agent inherits the class of the credential it presents. The consumer is never the counterparty.
  • Market status — a product type is a cosmetic, a drug, a special class or not permitted, market by market, with the regulator's page.
§04 · THE DOOR

The door

The Model Context Protocol (MCP) door of record is mcp.a2a-cosmetics.ai/mcp, a stateless streamable-HTTP server named a2a-cosmetics with 20 tools at version 1.0.0 (read from the door at build). Open schemas; the stock clients of the three major clouds attach with no adapter.

  • Gate (3) — resolve_jurisdiction Where is this going? Returns the market and rule set.; resolve_actor Who is asking? Brand, manufacturer, retailer or distributor.; gate_transaction Allow or deny, with the reason and the rule.
  • Regulatory truth (5) — get_ingredient_record One ingredient, and its status in every market.; get_market_status Is this product type a cosmetic here?; get_notification_requirements What must be filed before sale.; get_label_and_claims What the label must say, and which claims are allowed.; get_enforcement_watch Recalls, bans and safety alerts, dated.
  • Catalogue (3) — search_cleared_items Find products cleared for this market.; get_item One product by GTIN, fully resolved.; compare_items Compare products, variants and shades.
  • Supply (3) — find_verified_supplier Verified makers and brands for this product.; get_availability In stock, and where.; get_price The price for this buyer.
  • Documents (2) — get_product_documents Safety report, certificate of analysis, data sheet.; verify_gtin Is this GTIN real, and whose is it?
  • Commerce (2) — create_order_intent Open an order between two agents.; a2a_handoff Hand the buyer to the right agent.
  • Operations (2) — get_safety_label Warnings and age limits.; log_audit Write a line to the audit record.
§05 · THE RECORD

The record

Spine: the GSC SPARKS Beauty and Personal Care Taxonomy — four levels, then variant or form, then SKU / GTIN. Segments and claims are attributes, never branches.

  • Products — keyed by GTIN; taxonomy path; shades as parent and child so one product answers as one product.
  • Ingredients — by standard ingredient name (INCI), with status per rule set from the official lists.
  • Market status — product type by market: cosmetic, drug, special class, or not permitted.
  • Suppliers and retailers — brands and makers; banners, country, channel. A retailer record never implies the retailer buys through the hub.
  • Every record — carries claim_status: listed · claimed · verified. An unclaimed record answers: listed from public sources, not verified by the brand.
  • The showcase standard — every URL read live at load; dead, wrong or parked goes to the pond with its reason; only validated rows are served; every field carries its source; counts are read from the validated set at request time.

x402 is live: an order intent settles in USDC on Base after the gate; the receipt is signed and names what was bought, where and under which rule. The Machine Payments Protocol (MPP), the Universal Commerce Protocol (UCP) and the Agentic Commerce Protocol (ACP) are built and dark until they can settle; the Agent Payments Protocol (AP2) sits on the Agent Card.

  • a2a-pay.ai — the five rails in plain words, each with its door

  • a2a-registry.ai — the issuer: registration, tokens, keyring, revocation
