One protocol.
Every commerce action.
Search, inspect, check availability, build a cart, and hand off checkout. MCP-native tools, with a REST fallback for everything else.
Your agent brings the intent. We bring the products, fresh data, and a clear path to checkout.
// Find the right product, not another page.
relay.search({
query: "wireless headphones",
max_price: 200,
in_stock: true
})Not a website for your agent to navigate.
A commerce layer it can actually use.
Search, inspect, check availability, build a cart, and hand off checkout. MCP-native tools, with a REST fallback for everything else.
Partner catalogs, normalized into a single schema. Duplicate listings resolved before they reach your agent.
Price and stock refresh on a defined cadence. Stale offers stay out of the way. Final availability is confirmed by the partner.
Relay connects the steps.
You keep the experience.
The agent finds the right products, checks the details, and confirms price and stock.
relay.search → relay.detailSelected products and variants become a structured cart, tied to the agent and session.
relay.cart.createRelay creates an affiliate-tagged checkout link. The shopper completes payment with the partner.
relay.checkout.handoffThe partner records the transaction. Commission is reconciled to the originating agent and session.
agent_id + session_idStart with the assistant you already use. Connect once, then give your agent the tools to move from a recommendation to a real basket.
Add Relay to your MCP client configuration.

We're building the agent-native path to commerce.
The first decision? Which affiliate partner goes live on day one.
No. Relay is a structured commerce interface for AI agents. People complete their purchase through the affiliate partner's own checkout, not a Relay storefront.
They're separate products. Relay is a standalone agent-native marketplace; CRS keeps its own scope and identity. Any integration is a later chapter, not part of this launch.
This site is a developer preview. The playground uses sample data, endpoint examples are illustrative, and the first affiliate partner has not been announced. Live access follows partner onboarding and assistant validation.
The partner does. Relay creates the affiliate-tagged handoff and carries agent and session attribution. The partner confirms final price, availability, payment, delivery, and returns. Commission is subject to the partner's terms.
