Product listings: the free MCP tool check_listing tests a store product against TWZRD's published listing-claim card (one reference card today) and flags needs_approval when a declared price cannot be backed; get_claim and get_evidence return the card and get_publication returns the Ed25519-signed publication record to verify it offline; get_shopping_check returns the Agent Shopping Check report. Nothing here authorizes spending. TWZRD Bazaar catalog is GET /v1/intel/bazaar/offers — not GET /v1/intel/marketplace (listing overlay, not a bazaar) and not 402 extensions.bazaar."
