A2Apex is where AI agents earn trust.
Point it at any agent built on Google's A2A protocol and it runs 50+ automated compliance tests across 5 categories:
Agents earn a 0-100 trust score with Gold, Silver, or Bronze certification badges they can embed in READMEs, docs, or websites.
Every tested agent gets a public profile page in the Agent Directory with trust scores, capabilities, test history, and a live "Try This Agent" chat.
Built on Google's A2A Protocol โ the open standard for agent-to-agent communication with 22K+ GitHub stars.
Free tier: 5 tests/month. Pro: $29/mo unlimited.

A2Apex.io's answer:
A2Apex is the only platform that combines A2A protocol testing, certification badges, and an agent directory. It's not just a testing tool โ it's a trust layer where agents build reputation through verified compliance scores.
A2Apex.io's answer:
Nobody else focuses on Google's A2A protocol specifically. Competitors test APIs generically โ A2Apex understands A2A semantics: agent cards, task lifecycles, JSON-RPC messaging, SSE streaming. Plus, tested agents get listed in our public directory with embeddable trust badges.
A2Apex.io's answer:
Developers and teams building AI agents that need to communicate with other agents using Google's A2A protocol. Also companies evaluating third-party agents who want verified compliance before integrating.
A2Apex.io's answer:
Built by a dragline operator in Wyoming who saw Google's A2A protocol gaining traction (22K+ GitHub stars) with zero developer tooling around it. Classic picks-and-shovels play โ Google markets the standard, A2Apex builds what developers need to use it.

We work in an agency that develops websites mainly in WordPress, and regularly based on our experience over several years of working with multiple clients, we have discovered that one of the main problems between agency-client is communication, which often sometimes is tedious and fruitless, but now with the visual debugger is easy to point in the screen what needs to be changed and do it quickly. Also, we had a problem calculating how much our will cost our services for the customers according to the time spent on their projects but now with the "Time tracking" function, we can know exactly how much time was dedicated to the project and based on that invoice the client with greater certainty.
I think this is a great solution for web designers that needs to clear all visual bugs of a website fast to deliver in less time and get more jobs quickly.
