Inspiration

AI agents are everywhere, but there's no way to verify they actually work. No standard testing. No directory of trusted agents. No reputation system. Google's A2A protocol gives agents a shared language — but a shared language doesn't guarantee trust.

What it does

A2Apex is a testing, certification, and directory platform for AI agents built on Google's A2A protocol.

Test — Point it at any A2A agent URL. We run 50+ automated compliance checks: Agent Card validation, live endpoint testing, state machine verification, streaming, auth, error handling.

Certify — Agents receive a 0-100 trust score and earn Gold, Silver, or Bronze certification with embeddable badges.

Get Listed — Every tested agent gets a public profile in the Agent Directory with trust scores, skills, test history, and badges.

How we built it

Python/FastAPI backend, vanilla JavaScript frontend, SQLite storage. No React, no build tools. Built in 2 weeks (15,000+ lines of code) using an AI coding assistant, running on a Mac mini in Wyoming.

Challenges we ran into

The A2A spec is brand new — there were no reference implementations to validate against. We had to build the compliance test suite from the raw spec document.

What we learned

The moat isn't in the code — it's in shipping fast and understanding the problem deeply. AI tools made the building possible; domain knowledge made it valuable.

What's next for A2Apex

  • CI/CD integration for automated testing on every deploy
  • Python SDK (pip install a2apex)
  • Bulk testing for teams managing multiple agents
  • Historical trust score tracking
