A2A Experts · Agent-to-Agent Protocol
The A2A experts.
Agent-to-Agent expertise from someone who pioneered the AI-native web and runs a live A2A endpoint today. You get the strategy and the system itself, not a slide deck.
33 years of enterprise architecture behind every build. See it working on my own site, then put it to work on yours.
What A2A is
The protocol layer of the AI-native web
A2A (Agent-to-Agent) lets one AI system discover another and transact with it directly, machine to machine, with no human clicking through a website. The discovery file is agents.json, published at /.well-known/. If your business is not reachable this way, the AI agents that increasingly make buying and recommendation decisions cannot see you.

What I deliver
From discovery file to production system
01
A2A endpoints
Machine-readable endpoints other AI agents can discover and call, with a clean request and response contract and the guardrails to keep them safe.
02
agents.json & agent cards
Published at /.well-known/ so the agent ecosystem can find your service and transact with it, no human in the loop.
03
AI-native web & GEO
Sites built for the AI reader: schema, llms.txt, and content engineered so the models recommend and cite you.
Questions
A2A, in plain terms
What is the A2A protocol?
A2A, or Agent-to-Agent, is a protocol that lets AI systems discover and communicate with each other directly. Instead of a person browsing your website, another AI agent reads a machine-readable endpoint and transacts with your service. It is a foundation of the AI-native web.
What is agents.json?
agents.json is a discovery file published at /.well-known/agents.json. It tells other AI systems what your agent can do and how to call it, the way robots.txt or a sitemap guides search crawlers. It is how machines find your A2A endpoint.
Why does A2A matter for my business?
AI assistants are becoming the front door to the web. When a model answers a question or completes a task, it favors services it can read and reach. An A2A endpoint makes your business visible and transactable to those agents, not only to human visitors.
