# sm-amp-cpg.org — SM-AMP-CPG Sovereign Manifest · Agentic Marketplace Protocol for Consumer Packaged Goods. The machine-resolution protocol for agentic marketplaces. The Agentic Marketplace Protocol for Consumer Packaged Goods (AMP-CPG) is a deterministic, machine-readable protocol that enables an AI Agent to resolve the authoritative commercial endpoints for an identified product in a defined market. It answers one question: Given this product and this market, where can an Agent transact for it? One product. One market. One resolution set. Spec of record: https://sm-amp-cpg.org/spec.md Estate: 1 apex + 49 jurisdiction nodes = 50 nodes. Canonical surface per node = its .org; .com twins 308 to their .org; country door pages 308 to the apex — dark door, live service: /resolve answers on every node's own host. Design Law: No inference. No ranking. No checkout. No payment. No central hot path. Identify. Resolve. Verify. Route. Resolution is live on this node and all 49 jurisdiction nodes; publication is not open. Responses are signed (kid gsc-amp-2026-08) and verify from the public keyring at dpuone.ai. Third-party lodging is CLOSED and CEO-gated; GSC lodges GSC's records only. Resolve: GET https://sm-amp-cpg.org/resolve?gtin=&market= — market defaults to the node's market on a jurisdiction node. Responses are signed (compact detached JWS, kid gsc-amp-2026-08) and verify from the public keyring. Typed states: GTIN_UNRESOLVED / MARKET_UNRECOGNIZED / REQUEST_INCOMPLETE. OpenAPI description: https://sm-amp-cpg.org/openapi.json AMP-CPG does not own: price, inventory, checkout, payment, fulfillment, recommendation, negotiation — those remain authoritative at the commercial endpoint.
