UCP Checker
ucpchecker/ucp-checkerCheck whether any domain supports the Universal Commerce Protocol, find verified UCP storefronts by category or intent, and read their catalogs and policies. Every store is re-checked daily and linked to its public conformance record. Read-only: this server never creates carts or checkouts — you transact with the merchant directly.
