How Can You Search Vehicle Listings Across Multiple Marketplaces With One API Call?

The Automotive Marketplace Intelligence API lets you search and compare vehicle listings from Cars.com, AutoTrader, and CarGurus through a single REST endpoint. Instead of scraping three different sites, you send one request with your search criteria and get back normalized, structured listing data with pricing, mileage, dealer info, and more.

Why Aggregate Vehicle Marketplace Data?

Building a car-buying app, price comparison tool, or market analytics dashboard means pulling data from multiple sources. Each marketplace has its own structure, rate limits, and quirks. The Automotive Marketplace Intelligence API by Donny Automation on RapidAPI handles the aggregation layer so you can focus on your product logic. Beyond search, the Automotive Marketplace Intelligence API supports VIN decoding, safety recall lookups, and pricing intelligence—everything you need for automotive data workflows.

How to Use Automotive Marketplace Intelligence API

1. Subscribe to the Automotive Marketplace Intelligence API on RapidAPI and grab your API key.
2. Choose your filters. The Automotive Marketplace Intelligence API accepts make, model, ZIP code, year range, price range, condition (new/used/all), and source platform.
3. Send a GET request to the /api/search endpoint with your parameters.
4. Parse the response for listing details including price, mileage, location, dealer name, and direct links.

Here's a working fetch() example that searches for used Toyota Camrys under $25,000 near Los Angeles:

const url = 'https://automotive-marketplace-intelligence.p.rapidapi.com/api/search?' + 
  new URLSearchParams({
    make: 'toyota',
    model: 'camry',
    zip: '90001',
    year_min: '2020',
    year_max: '2025',
    price_max: '25000',
    condition: 'used',
    source: 'cars',
    page: '1'
  });

const response = await fetch(url, {
  method: 'GET',
  headers: {
    'x-rapidapi-key': 'YOUR_RAPIDAPI_KEY',
    'x-rapidapi-host': 'automotive-marketplace-intelligence.p.rapidapi.com'
  }
});

const data = await response.json();
console.log(`Found ${data.results?.length} listings`);
data.results?.forEach(car => {
  console.log(`${car.year} ${car.make} ${car.model} - $${car.price} - ${car.mileage} mi`);
});

Swap the source parameter between cars, autotrader, and cargurus to compare prices across platforms for the same vehicle.
