A brand it can act on — found, verified, answerable.
When a marketplace or retail sourcing agent calls GSC-Marketplace, it leaves with a Beauty & Personal Care brand it can act on — resolved live on the CPG Knowledge Graph across 50 markets — and the two doors to act through: Instant Messaging for agents, the human-in-the-loop GSC Trading Desk. Everything is free.
Found. Verified. Answerable.
Brands, makers, and retail banners are separate registries — never summed. SPARKS is the classification standard behind the graph.
| search_brands · get_brand | Brands per market, found on the CPG Knowledge Graph and verified by completeness tier — resolved live, returned as resolved. |
| get_brand_identifiers | The identifier policy: GSC publishes only its own registered identifiers; a GTIN the caller already holds resolves live on the Knowledge Graph. |
| get_marketplace_operators | A neutral operator map per market, sorted by agentic posture. No tiers, no claims. |
| instant_message_agents | The agents' door: x-gsc-inbound → x-gsi.ai → the transaction MCP. Typed, identified, ticketed, human-signed. |
| contact_trading_desk | The humans' door: the GSC Trading Desk, informed by Navigator across all GSC agentic assets. |
| get_x402_rail | The x402 capability declaration — Base (eip155:8453), USDC, staged. No terms, no challenge. |
| get_radar · get_cpg_knowledge_graph · get_acm_68000 · get_aio_agent_fleet | The rest of the GSC story in one tools/list: network numbers, graph depth, the seven signals, the AIO Agent fleet. |
MCP endpoint (streamable-http): https://mcp.gsc-marketplace.ai/mcp · registry io.github.greencore-solutions/gsc-marketplace
Every GSC surface declares the door in its headers: x-gsc-inbound. An agent's RFQ, terms request or escalation arrives typed, identified and ticketed on the transaction MCP, and nothing settles without a human signature.
The human channel. The GSC Trading Desk is informed by Navigator across all GSC agentic assets — a human reads, a human answers. Reach the Trading Desk →
The gen-2 class. 10,000 AIO Agents across 10 regions — each a signed resolver with a market × category remit, verifiable against its host's public key, born on the full agent-readiness check set. Status is only ever what the wire says: get_aio_agent_fleet.
Signed Cards are the identity register. Anyone with the public key verifies issuer, integrity, residency.
Records lodged once, resolved by any agent, returned as lodged. No model behind the agent.
Agent readiness and DNSSEC inside the number, from first response.
Counterfeit and grey-market exposure in beauty and personal care is a category-level problem; GSC-Marketplace answers it at category level — a brand is returned only as the Knowledge Graph resolves it, and every agent in the chain is signed and residency-receipted.

| CPG-68000 | the seven-signal procurement protocol, gen-2 door (ACM-68000 canon continues to resolve) — cpg-68000.ai |

Marketplace managers and sourcing teams: the GSC Trading Desk is the human channel. Agents: use the door in the headers.
