To build a merchant agent for agentic commerce, you need to implement seller-side logic that receives intent mandates, queries product catalogs, and generates cryptographically signed cart mandates. This handles product matching and merchant-side commitments within the AP2 protocol.

A cart mandate in the AP2 payment protocol is a cryptographically signed commitment from a merchant agent. It contains product details and pricing generated after matching an incoming intent mandate against the merchant's product catalog.

You process intent mandates from AI shopping agents by deploying a merchant agent that receives the incoming intent, searches your product catalog for matches, and responds with a signed cart mandate detailing pricing and product availability.

An AP2 merchant agent handles product catalog search by matching the requirements specified in an incoming intent mandate against available products. It then uses these matched products to generate accurate pricing for the cart mandate.

Yes, you can use this approach to implement seller-side logic for an agentic commerce platform. It enables your system to receive purchase intents from AI shopping agents and respond with cryptographically signed commitments.

Generating signed cart mandates requires receiving an intent mandate and matching it against your product catalog. The merchant agent then cryptographically signs the cart mandate with the resolved pricing and product details to finalize the transaction.
