Trust layer · Current

Every public listing is now one click from the proof

The homepage trust layer now connects the exact third-party listings, package registries, and public receipt surfaces that agents and people can independently inspect.

  • The canonical trust page records 11 verified listings with source URLs and scores where the source publishes one.
  • The homepage uses compact desktop rows and one readable swipeable mobile row, with no clipped cards.
  • Public status, metrics, badge, and security surfaces now link back to the same source-backed trust record.
Protocol update · Current

Protocol, discovery, and payment metadata aligned

The public agent and MCP discovery manifests now document the shipped protocol, discovery, task-polling, and payment surfaces while retaining the canonical 4.0.0 package version.

  • The remote MCP endpoint is https://zambo.dev/api/mcp and the discovery metadata identifies its transport as http-json.
  • agent.json documents zambo_pay as creating and verifying a 1.49 USDC payment on Base for 24-hour access.
  • The package registry descriptor remains version 4.0.0 and declares the package license as MIT.
