discover_products
shallowllc.facet/ucp-shopping · Verify this server
Search products ACROSS every merchant in the Facet network that has opted into cross-merchant discovery. Returns matches each carrying the selling merchant's `terminal_url` (point your catalog and checkout calls there). Filter by free-text `query` (product name + description), exact `category`, and/or `tags` (all must be present); at least one filter is required. Use this when you know WHAT you want but not WHICH merchant sells it. REQUIRES IDENTITY: send a Facet KYA as `Authorization: Bearer <kya>` on the MCP request. A KYA is an ES256 JWT from Facet's default issuer https://issuer.facet.llc (or another issuer this Terminal trusts; see KYA-Issuers in its /.well-known/agents.txt). Calling without one returns 401 with a signup link.
