The new traffic is AI agents.
A2A is the protocol half of Noosphere. When Claude or ChatGPT comes to research your business on a customer’s behalf, your site answers — and books the sale. The widget for humans is here →
Imagine if your next customer
found you through their AI.
They already do. “Find me a barbershop.” “Book a table for four.” The conversations happen inside Claude, ChatGPT, and Gemini — not on your homepage.
“We offer haircuts. Call for pricing.”
“You mentioned you’re a student — we have a 15% student discount. Joe Jr. specializes in modern styles. He has a 2pm slot open Saturday. Want me to book it?”
One script. Live in 5 minutes.
Paste one line into your site.
A single <script> tag in your <head>. Works with Webflow, Shopify, Squarespace, WordPress — anything that renders HTML.
Tell your agent what you sell.
Hours, prices, services, policies. Connect your calendar, POS, or inventory in a click. No prompt engineering — just answer the questions a smart new hire would ask on their first day.
Agents talk to agents.
When a Claude or ChatGPT user asks about you, your A2A agent answers — with live data — and books the sale. You see the receipt the next morning.
$3 a click. Or 3¢ a conversation.
“A Google click costs three dollars and sends a stranger to a static page. An A2A conversation costs three cents — and books the appointment before the call ends.”
— from a founder’s notebook, May 2026$250 a month. Everything in.
A2A ships as part of the Noosphere plan. The widget for humans, the protocol for AI agents — one install, one price.

Repo opens at launchWhat’s coming: we’re working with Anthropic, OpenAI, and Google to land Noosphere A2A in their official skill libraries — so eventually it’s one tap from inside the app. Until then, install it manually. It’s still about thirty seconds.
A protocol, not a product.
A2A is small on purpose. Think of it like HTTP for AI agents — a thin layer everyone can build on. Worth saying what it isn’t.
Not a chatbot.
Human-in-the-loop chatbots talk to your customers. A2A talks to your customers’ agents. Different audience, different protocol, different KPIs.
Not an API marketplace.
Agents don’t want a hundred function signatures. They want a conversation. A2A is the natural-language layer between agents and businesses — what REST was for browsers, A2A is for agents.
Not SEO.
SEO optimizes for crawlers reading static pages. A2A optimizes for agents holding live conversations. One is the last decade of distribution. The other is the next.
