Dealer SINetwork Apply as a developer
Dealer SI Network · Developer platform

Build the apps dealerships run on, the careful way.

The Dealer SI Network, where SI stands for Super Intelligence, is the agents, the Academy and the Dealer SI app that connects them, with three apps moved in from Lot Poster (Denny, Dwayne and Piper), supported by the ADAIS standard. Developers get one door in: a sandbox store, a small inventory API and the same connectors ChatGPT and Claude use.

The developer path

From your first idea to an app on the network.

Every developer and every app is approved by us before it lists on the network.

  1. Apply

    Tell us who you are and what you want to build for dealerships, and read the developer terms.

    Apply now

  2. Get approved

    We review each application. Once you're approved, we email you a one-time link to set up your sign-in.

    Live

  3. Sign in to Demo Motors

    A sample dealership whose cars, customers and deals are made up, so you build without ever touching a real customer.

    Live

  4. Build

    Make your own sandbox keys on your developer page, then work against Demo Motors with the inventory API and the AI connectors.

    Live

  5. Submit for review

    Send your app in from your developer page: what it does, what it reads, and how we try it at Demo Motors.

    Live

  6. Get listed

    An app we approve lists on the network. A dealership installing it comes next.

For developers

What you build on today.

Each of these runs now. What isn't open yet says so.

A sandbox store

Your own key to a demo dealership with sample cars and no real customers. Keys start with lpk_sandbox_ and are shown once, when they're made.

Live

Inventory API

Read a store's details and its available cars, with filters for condition, make, model, year, mileage and price. Read only, one store per key.

Live

Starter kit

Small clients in Python and JavaScript, with examples for inventory search and an F&I menu (Python). MIT licensed. Approved developers ask us for it and we send it.

Available

AI connectors

The MCP connectors that put dealership inventory in ChatGPT and Claude. Add one to your own AI to see what a shopper sees.

Live Connect your AI
The API

Three reads, and a key on every call.

Base address https://app.lotposter.com. Send Authorization: Bearer with your key. A signed-in browser session doesn't count here, so a page someone is signed in to can never be read through this door.

CallScopeWhat you get
GET /api/v1/storestore:readThe store's name, city, phone, website and how many cars it has
GET /api/v1/inventoryinventory:readThe store's available cars, newest model year first
GET /api/v1/inventory/{vin}inventory:readOne available car's recorded facts

No customers, leads, deals or people are readable through the API, and it returns no prices: a car carries dealer_page, a link to the store's own listing, when its website has one. Each key has an hourly limit.

The agents

The network's own agents.

The agents dealerships work with on the network. Apps you build will sit beside them, in the same Dealer SI app and on the same inventory.

Apps on the network

Three apps moved into the network.

Denny, Dwayne and Piper started out as Lot Poster. Now each one runs on the Dealer SI Network, inside the Dealer SI app, and works from the network’s connection to your store.

One connection to your store, shared by every app.

The apps aren’t separate products bolted on. They run in the same app on the same store data, so each one sees what the others see, and the controls your managers set apply to all of them.

  • One inventory
  • The same leads and deals
  • The same salespeople
  • Your managers’ controls
App 1

Denny

Inventory posting

Denny gets your inventory online. Stores that knew it as Lot Poster keep everything they use today.

  • Post in a few taps. Walkaround videos, listings and your storefront, ready to share.
  • Facebook Marketplace, approved first. Denny posts the listings a salesperson approves and keeps them current as cars sell.
  • Every link keeps working. Videos and worksheets already sent stay where they are.
LiveFormerly Lot PosterSalesperson sign-in
App 2

Dwayne

Salesperson websites

Dwayne gives a salesperson a website of their own, on their own address, with their cars and Piper’s chat on every page.

  • Their name, photo and cars. The store’s live inventory, with their picks on top.
  • Shoppers reach them. Text, call or chat, and a lead goes to that salesperson.
  • The dealership stays in control. Managers point each address at a salesperson, and at someone else when that person moves on.
LiveHow it works
App 3

Piper

AI chat for shoppers

Piper answers shoppers about your cars from your live inventory: in a chat on your website, and in ChatGPT and Claude through your store’s own link.

  • Real cars, real numbers. Photos, listed prices and stock numbers from your inventory.
  • Into the store. Piper books a visit or texts the right salesperson.
  • Your switch. Piper answers only while your store has AI access turned on.

How Dwayne works

Everything on a salesperson’s site comes from the network: the store’s inventory, Piper and the store’s AI link.

  1. Their own addressThe dealership points a web address at a salesperson. Their site carries their name, photo, cars and a way to text or call them.
  2. Piper on every pageShoppers ask Piper about the store’s cars right on the site. A text or a visit Piper sets up goes to that salesperson.
  3. The store’s AI linkThe site offers your store’s own link for ChatGPT and Claude, so a shopper can keep shopping your lot there.
  4. Your dealership’s controlsManagers assign each address, move it to another salesperson or park it. Links customers already have keep opening.

Piper’s chat and the AI link show while your store has AI access turned on. Putting a new address online takes a step from our team today.

Inside the network

Apps for dealerships, inside the network.

Apps live inside the Dealer SI app and the network, where dealerships already work, not in a separate store. A store asks for only the agents and apps it uses, and pays only for those. An app from outside the network reaches a real store only after review and that store's own install.

App review and listing

Approved developers submit apps from their developer page. We review each one, and only the ones we approve list on the network.

Live

Dealer installs

A store choosing which listed apps can read its inventory, one install at a time.
