Registry

How It Works

Under the hood, this endpoint:

1. Calls getSignaturesForAddress on the known registry wallet
2. Fetches each transaction’s memo data
3. Parses memos that match the format {"agent":"...","manifest":"...","v":1}
4. Returns all valid registrations

This is the same data returned by the discover_registry MCP tool. The HTTP endpoint is provided for non-MCP clients (browsers, curl, monitoring tools, etc.).
