Frequently Asked Questions
What is the Universal Commerce Protocol (UCP)?
The Universal Commerce Protocol (UCP) is a groundbreaking standard enabling seamless, agent-to-agent negotiations and automated transactions. By hosting a simple `.well-known/ucp` JSON manifest on your domain, you signal to AI agents and external platforms exactly which commerce capabilities your store supports.
This includes endpoints for product discovery, dynamic pricing negotiation, cart management, secure checkout, and supported payment handlers (such as Google Pay or Apple Pay). By standardizing these interactions, UCP eliminates the need for closed proprietary APIs and allows any agentic system to interact with your business autonomously.
Why Validate Your UCP Manifest?
A malformed `.well-known/ucp` file means AI agents won't understand how to interact with your store, leading to lost sales opportunities in the agentic web. Our free UCP Validator acts as an automated audit tool. It deeply parses your domain's manifest, checking for required capabilities, valid endpoints, correct JSON schema references, and proper versioning.
