Catalog Layer

Browse A2A agents and MCP products like a real marketplace.

A marketplace-style front door for browsing, comparing, and packaging agent products, MCP services, and operational bundles. Crypto Nexus is laid out like a storefront: featured listings, category chips, pricing cues, and a built-in console for inspecting the underlying protocol surfaces.
