Auto Agent Protocol hits 1.0 — and we're connecting 1,000 dealerships for free

A few months ago, I wrote about a simple idea: what if your AI could actually buy you a car?

The short version was this. Buying a car is still painful for everyone. Buyers open ten tabs, see ten different prices, and fill out the same form six times. Dealers drown in junk leads and never know which one is real. So we built a small, open standard that lets any AI agent talk to any dealership in the same language. We called it the Auto Agent Protocol, or AAP.

Back then, AAP was version 0.1. It was new. It was narrow on purpose. And I made one promise: we would not expand it until the foundation was rock solid and real dealers were running on it.

Today, I'm happy to share that the foundation is done.

Auto Agent Protocol is now 1.0. Stable. Locked. Ready to build on.

And to celebrate, we're connecting the first 1,000 dealerships to it — for free, forever.

Let me explain what all of that means in plain words.

What "1.0" actually means

In software, a "1.0" release is a quiet but big deal.

Before 1.0, a standard can change under your feet. You build something on Monday, and by Friday the rules are different. That's fine for experiments, but no serious business wants to build on shifting sand.

A 1.0 says: this is stable now. The shape of the messages, the names of the fields, the rules of the contract — they're set. If you build on AAP today, it will still work tomorrow. We'll keep adding new things in future versions, but we won't break what already works.

For a dealer, this is the green light. For a CRM, DMS, or inventory company, this is the moment it's safe to wire AAP into your product. The contract is finished, written down, and free for anyone to read at autoagentprotocol.org.

The whole thing is still small on purpose. AAP 1.0 gives an AI agent exactly five things it can ask a dealership:

1. Tell me about your dealership — where you are, your hours, your brands.
2. What kind of inventory do you have? — rough counts, price ranges, years.
3. Show me cars that match — find a 2022 or newer Honda CR-V under $30,000.
4. Tell me everything about this one car — full detail on a single vehicle.
5. Here's a real customer who wants to come in — a clean lead, with the customer's consent, a trade-in if there is one, and a test drive booking.

That's it. Five things, done right. No checkout. No payments. No fluff. Just the part that actually matters: let an AI find the right car at your store and hand you a ready-to-work customer.

Why we're giving it away to 1,000 dealerships

Here's the thing about an open standard: it's only useful if enough people speak it.

A language with one speaker is just noise. The value shows up when an AI agent can knock on a thousand dealership doors and get a clear answer at every one. That's good for buyers, who get real choices. And it's good for dealers, who get found.

So we decided to remove the only thing standing in the way: cost.

The first 1,000 dealerships we connect to Auto Agent Protocol pay nothing. Not now, not later. Free, forever. No setup fee. No monthly fee. You're simply in — early, and for good.

Why would we do this? Because we'd rather have a living, breathing network of real dealerships than a perfect price list. The standard wins when dealers win. Simple as that.

And don't worry about the technical side — we handle it. Getting connected takes three small steps, and we do the heavy lifting on all of them:

1. One small file on your website. We give you the content; it lives at a single address (/.well-known/agent-card.json). Think of it as a sign on your door that tells AI agents "yes, you can talk to me, and here's how."
2. Tell us where your inventory lives. Just name your inventory provider and we'll reach out to them directly. Or, if it's easier, send us a feed and we'll help you set it up.
3. Give us your leads email. The one your CRM or DMS already uses. Leads from AI agents arrive in the same standard format (ADF) your team already works with every day. Nothing new to learn.

That's the whole job. You don't write code. You don't change your CRM. You don't train your staff on a new screen. You just start showing up when an AI goes looking for a car.

Why this matters — for both sides

I'll keep this short, because the first article goes deep. But the heart of AAP is fairness, and it's built into the rules, not bolted on after.

• Honest prices. Every car has a final, out-the-door price — the number a buyer actually pays. No bait prices. The protocol won't let an agent quote a fake low number.
• Real consent. A lead can't even be sent without the customer's written "yes" attached — when they agreed, and to what. Easier on the rules for dealers. Fewer unwanted calls for buyers.
• Real inventory. Agents see what you actually have today, not a stale page from last month.

Buyers stop being the data-entry intern in their own car search. Dealers stop guessing whether a lead is real. Both sides win, which is the only kind of fix worth building.

Why this is the future

For twenty years, "progress" in car retail mostly meant a slightly nicer website. AI changes the shape of the whole thing.

The next front door to a dealership isn't a website. It's a conversation — and one side of that conversation is an AI assistant. People are already asking ChatGPT and other assistants to find things for them, compare them, and book them. Cars are next.

When that happens, dealerships that speak AAP will simply be there — readable, sortable, recommendable. Dealerships that don't will be invisible to that whole new channel, the same way a business with no website was invisible in 2005.

And we built 1.0 ready for that world. AAP now speaks the language of modern AI tools out of the box, including MCP — the way assistants like Claude connect to outside services. So when an assistant wants to shop for cars, it can use AAP directly.

There's more coming, and I'll say it plainly: we'll soon announce a non-profit ChatGPT app and Claude connectors built on Auto Agent Protocol. The goal isn't to be another middleman taking a cut. The goal is to help both sides — buyers and dealers — and make the whole process simpler, more honest, and more convenient. That's the entire point.

How to get in

If you run a dealership, or you build CRM, DMS, or inventory software, here's how to join:

• Want one of the 1,000 free spots? Leave a comment here or email us at aap@lumika.ai, and we'll walk you through it. We do the setup.
• Want to read the rules first? The full 1.0 spec is open and free at autoagentprotocol.org.
• Want to build on it? It's open source under Apache-2.0. Read it, use it, suggest changes.

The first 1,000 are free forever. After that, the door stays open — just not for free.

We started this because we sit on both sides of the table. We build the software dealers use, and we build the AI agents that talk to dealers. We see both headaches. And we still believe the fix is the same one we bet on from day one: a small, clean, honest contract — given away to the whole industry.

It's stable now. It's real now. And for the first 1,000 dealerships, it's free.

Let's make it easier. For everyone.
