UCP Checker

A validator and monitoring service for the Universal Commerce Protocol that checks merchant manifests against the spec, grades agent-readiness, and verifies catalog and checkout behavior for AI shopping agents. It is for developers, operations teams, and businesses that operate ecommerce storefronts and need to ensure discoverability by AI assistants. It is positioned as an independent, neutral measurement layer that tests both declared manifests and live agent runtime behavior on a continuously re-crawled index.
