ucp-merchant-agent

You can scaffold a Python A2A agent for UCP merchant checkout by running the provided script, which generates a project template for discovering merchant capabilities, creating checkout sessions, and handling payments. The template includes FastAPI, httpx, and pydantic.

Yes, the UCP merchant agent supports automating AP2 or 3DS payments across multiple merchants. It provides sample handlers and templates that demonstrate Google Pay, direct tokenization, and AP2 mandates within the checkout workflow.

The UCP merchant agent requires Python 3.10 or higher. You also need standard libraries plus dependencies listed in the templates, specifically FastAPI, httpx, pydantic, and python-dotenv to bootstrap and run the agent.

To scaffold an A2A shopping agent, run `python scripts/create_ucp_agent.py my-shopping-agent --path ./agents` from the project root. This script bootstraps a new agent directory with configuration files and reference docs to accelerate integration.

Yes, the UCP merchant agent automates checkout session negotiation. It applies to discovering merchant capabilities, negotiating terms, creating checkout sessions, and completing payments across the UCP network.

Use the template-driven agent when you need a ready-to-use framework for building Python-based A2A agents that interact with UCP merchants, enabling automated discovery, checkout session management, and payments without starting from scratch.
