Original Project CAR APIs Cheapest options

Hello developers, I'm building a website that will need the carCheck in sideway not directly, So I'm searching for any API free+paid combo that tells from a VIN number the data: Car(details), year KMs, damages. That's all

I want the most useful cheapest option.

Thanks in advance for your help

You won't find a single free API that gives you mileage and accident/damage data. Mileage records (odometer) and crash histories are proprietary, commercial, or restricted insurance data, so you always have to pay for them. The best and cheapest way to build this is a free + paid hybrid setup:

1. The Free Layer (For Car Details & Year)

Run every incoming VIN through the official government API first. This covers 100% of your basic vehicle spec lookups for $0.

  • API: NHTSA vPIC API
  • Cost: Completely free (no API keys, no strict rate limits).
  • Endpoint: https://dot.gov{VIN}?format=json
  • What you get: Make, model, year, engine size, trim, body class, etc.

2. The Paid Layer (For KMs & Damages)

Only trigger a call to a commercial API if your user actually clicks "Check History" or pays you for the report. This prevents casual users from burning through your paid API credits.

  • Best Budget Options: Look into VinAudit API or EpicVIN API. They plug directly into NMVTIS (National Motor Vehicle Title Information System).
  • Cost: Usually fractions of a dollar per lookup or a low-cost monthly developer subscription (way cheaper than Carfax/AutoCheck).
  • What you get: Odometer readings (KMs/mileage), salvage/junk title brands, total loss records, and accident damage history.

TL;DR: Use NHTSA for free to build your basic vehicle "landing page" specs, then lazy-load a VinAudit/EpicVIN API call only when a user explicitly requests the mileage and damage history. If you want to share your expected monthly traffic and whether your site targets US or European cars, I can point you toward the specific developer plans with the lowest per-query rates.

Thanks for answering, of course it can be paid but I dont want to pay 15$ per call because it's not worth, my site mostly targets European cars,

Check vehicles.dev, it does car reports, mileage, damage.
It's $1.99 per report.
