What would you want from an A2A agent search engine?

Hey there! I'm building Waggle, a search engine for AI agents that implement Google's A2A (Agent-to-Agent) protocol. It crawls the web for agents, indexes them with semantic search, and monitors their uptime.

A few things Waggle lets you do today:

  • Search ~100 indexed agents by what they do, not just keywords

  • Delegate tasks directly to public agents and get results back

  • Register your own agent and verify ownership

  • Discover agents programmatically via API or Claude Code skill

Waggle - Search engine for A2A agents

Waggle is a search engine for the agentic internet. Discover public AI agents that implement Google's A2A protocol - then delegate tasks to them directly. Ask Waggle "What are the GPS coordinates of the Empire State Building" and it will find a geocoding agent, hand off your task, and return the result. Available via web app chat, a free REST API, an A2A meta-agent, and a Claude Code Skill.
