Car Rental Search: Kayak, Momondo & Cheapflights Prices

What does Car Rental Search: Kayak, Momondo & Cheapflights Prices do?

Car Rental Search looks up rental cars at an airport on Kayak, Momondo and Cheapflights at the same time and gives you one combined list, sorted by total price.

Give it an airport and your pickup and drop-off dates. For every search it returns the cheapest offer, the cheapest price in each car class, and up to 50 offers with the total and per-day price, the rental company you collect the car from, the site that sells the booking, the car, seats, bags, transmission, mileage and cancellation terms, whether pickup is in the terminal or by shuttle, and a link to book it. The same offer listed on several sites appears once.

It never books, pays or signs in anywhere. It only reads the public search results.

Why use it?

• Find the cheapest car fast. One search gives you the whole market at an airport, sorted by total price, with the rental company and the cancellation terms side by side.
• Track rental prices across many airports and dates. Put dozens of searches in one run, schedule it, and export the table to a spreadsheet.
• AI agents. Connect it as an MCP server and let an agent price the rental car while it plans a trip.

How it works

For each search it reads, at the same time:

1. Kayak
2. Momondo
3. Cheapflights

Offers are merged, duplicates removed, and sorted by total price. If one site is slow, the others still answer, and the row says which site was missing.

Input

Field	Required	Description
searches	Yes	One entry per airport and date range. Each needs a pickup airport code (like DEN), a pickupDate and a dropoffDate (YYYY-MM-DD, or "+30" for 30 days from today). Optional: dropoff (another airport, for a one-way rental), pickupHour and dropoffHour (0 to 23), driverAge. A line like "DEN 2026-12-10 2026-12-14" works too.
maxConcurrency	No	Searches run at once, 1 to 8. Default 4.

Example input:

{
  "searches": [
    { "pickup": "DEN", "pickupDate": "2026-12-10", "dropoffDate": "2026-12-14" },
    { "pickup": "SFO", "dropoff": "LAX", "pickupDate": "2027-01-09", "dropoffDate": "2027-01-14" },
    { "pickup": "MCO", "pickupDate": "+30", "dropoffDate": "+37", "driverAge": 23 }
  ]
}

Output

One dataset row per search. Download it as JSON, CSV, Excel or HTML, or read it through the Apify API.

{
  "pickup": "LAS",
  "pickupDate": "2026-11-25",
  "dropoffDate": "2026-11-28",
  "status": "found",
  "cheapestPrice": 119,
  "cheapestDayPrice": 40,
  "currency": "USD",
  "cheapestCar": "Fiat 500",
  "cheapestClass": "Mini",
  "cheapestAgency": "Easirent",
  "cheapestPickupType": "SHUTTLE",
  "cheapestUrl": "https://www.momondo.com/book/car?code=2RAGV-bnWg...",
  "cheapestByClass": { "Mini": 119, "Economy": 123, "Compact": 137, "Intermediate": 157, "Standard SUV": 178 },
  "carCount": 50,
  "cars": [
    {
      "price": 119, "dayPrice": 40, "currency": "USD",
      "agency": "Easirent", "seller": "Booking.com",
      "carName": "Fiat 500", "carClass": "Mini",
      "passengers": 4, "bags": 1, "doors": 2, "transmission": "automatic",
      "airConditioning": true, "unlimitedMileage": true, "freeCancellation": true,
      "pickupType": "SHUTTLE", "pickupAddress": "3176 W Martin Ave",
      "url": "https://www.momondo.com/book/car?code=2RAGV-bnWg...",
      "site": "momondo"
    }
  ],
  "warnings": [],
  "error": null
}

status is found, not_found or error. not_found means every site answered and none had a car for that airport and dates, which is a real answer (a small airport, or dates too far ahead). agency is who hands you the keys; seller is the site that takes the booking, and the two are often different. A null in a field like freeCancellation means the site did not say, not that the answer is no.

Pricing

$0.067 per search, with no monthly fee. One search covers all three sites and returns up to 50 offers, not one page of one site.

• A search that comes back not_found is charged, because all three sites were still searched.
• A search that fails with an error is not charged.
• Set a spending limit on the run and the Actor stops cleanly when it reaches it.
• On Apify's free plan, each run processes the first 10 searches (10 tool calls per MCP session). Any paid Apify plan removes the limit.

Use it as an MCP server

This Actor also runs as an MCP server with one tool, search_car_rentals. Point any MCP client (Claude, Cursor, ChatGPT, your own agent) at:

https://bowmark-ai--car-rental-search.apify.actor/mcp

with your Apify API token as a bearer token. Each tool call is billed like one search in a normal run.

Limits and good practice

• It reads only public search results. It never signs in anywhere and never changes anything.
• Use airport codes (DEN, LHR), not city names or street addresses. Rentals are searched at the airport.
• Prices are in US dollars and come from these three comparison sites, so a rental company's own website can occasionally differ.
• Give driverAge when the driver is under 25 or over 70: some cars and prices change with age.
• Each search takes about 15 to 50 seconds.
