UCP Checker

list-stores

List verified UCP stores, optionally filtered by category and minimum score. Use when the user wants to shop by category — e.g., "find me a pet store" or "what shoe stores are available?" Returns stores sorted by score (highest first) with domain, category, score, and grade.
