To get started with the CarsXE API, follow these steps:

1. Sign up for a CarsXE account:

   • Register here
   • Add a payment method to activate your subscription and get your API key.

2. Install the CarsXE NuGet package:

   Run this command in your terminal:

   dotnet add package carsxe

3. Import the CarsXE API into your code:

   using carsxe;

4. Initialize the API with your API key:

   string API_KEY = "YOUR_API_KEY";
   CarsXE carsxe = new CarsXE(API_KEY);

5. Use the various endpoint methods provided by the API to access the data you need.

Usage

string vin = "WBAFR7C57CC811956";

try
{
    var specs = carsxe.Specs(new Dictionary<string, string> { { "vin", vin } }).Result;
    Console.WriteLine("API Response:");
    Console.WriteLine(specs.RootElement.GetProperty("input").GetProperty("vin").ToString());
}
catch (Exception ex)
{
    Console.WriteLine($"Error: {ex.Message}");
}

📚 Endpoints

The CarsXE API provides the following endpoint methods:

Specs – Decode VIN & get full vehicle specifications

Required:

• vin

Optional:

• deepdata
• disableIntVINDecoding

Example:

var vehicle = carsxe.Specs(new Dictionary<string, string> { { "vin", "WBAFR7C57CC811956" } }).Result;

---

InternationalVinDecoder – Decode VIN with worldwide support

Required:

• vin

Optional:

• None

Example:

var intvin = carsxe.InternationalVinDecoder(new Dictionary<string, string> { { "vin", "WF0MXXGBWM8R43240" } }).Result;

---

PlateDecoder – Decode license plate info (plate, country)

Required:

• plate
• country (always required except for US, where it is optional and defaults to 'US')

Optional:

• state (required for some countries, e.g. US, AU, CA)
• district (required for Pakistan)

Note:

• The state parameter is required only when applicable (for specific countries such as US, AU, CA, etc.).
• For Pakistan (country='pk'), both state and district are required.

Example:

var decodedPlate = carsxe.PlateDecoder(new Dictionary<string, string> 
{ 
    { "plate", "7XER187" }, 
    { "state", "CA" }, 
    { "country", "US" } 
}).Result;

---

MarketValue – Estimate vehicle market value based on VIN

Required:

• vin

Optional:

• state

Example:

var marketvalue = carsxe.MarketValue(new Dictionary<string, string> { { "vin", "WBAFR7C57CC811956" } }).Result;

---

History – Retrieve vehicle history

Required:

• vin

Optional:

• None

Example:

var history = carsxe.History(new Dictionary<string, string> { { "vin", "WBAFR7C57CC811956" } }).Result;

---

Images – Fetch images by make, model, year, trim

Required:

• make
• model

Optional:

• year
• trim
• color
• transparent
• angle
• photoType
• size
• license

Example:

var images = carsxe.Images(new Dictionary<string, string> 
{ 
    { "make", "BMW" }, 
    { "model", "X5" }, 
    { "year", "2019" } 
}).Result;

---

Recalls – Get safety recall data for a VIN

Required:

• vin

Optional:

• None

Example:

var recalls = carsxe.Recalls(new Dictionary<string, string> { { "vin", "1C4JJXR64PW696340" } }).Result;

---

PlateImageRecognition – Read & decode plates from images

Required:

• imageUrl

Optional:

• None

Example:

var plateimg = carsxe.PlateImageRecognition("https://api.carsxe.com/img/apis/plate_recognition.JPG").Result;

---

VinOcr – Extract VINs from images using OCR

Required:

• imageUrl

Optional:

• None

Example:

var vinocr = carsxe.VinOcr("https://api.carsxe.com/img/apis/plate_recognition.JPG").Result;

---

YearMakeModel – Query vehicle by year, make, model and trim (optional)

Required:

• year
• make
• model

Optional:

• trim

Example:

var yymm = carsxe.YearMakeModel(new Dictionary<string, string> 
{ 
    { "year", "2012" }, 
    { "make", "BMW" }, 
    { "model", "5 Series" } 
}).Result;

---

ObdCodesDecoder – Decode OBD error/diagnostic codes

Required:

• code

Optional:

• None

Example:

var obdcode = carsxe.ObdCodesDecoder(new Dictionary<string, string> { { "code", "P0115" } }).Result;

---

Async/Await Usage (Recommended)

For better performance and non-blocking operations, use async/await instead of .Result:

using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using carsxe;

class Program
{
    static async Task Main(string[] args)
    {
        string API_KEY = "YOUR_API_KEY_HERE";
        await using var carsxe = new CarsXE(API_KEY);

        try
        {
            var specs = await carsxe.Specs(new Dictionary<string, string> { { "vin", "WBAFR7C57CC811956" } });
            Console.WriteLine("Year: " + specs.RootElement.GetProperty("attributes").GetProperty("year").ToString());
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Error: {ex.Message}");
        }
    }
}

Notes & Best Practices

• Parameter requirements: Each endpoint requires specific parameters—see the Required/Optional fields above.
• Return values: All responses are JsonDocument objects for easy access and manipulation using System.Text.Json.
• Error handling: Use try/catch blocks to gracefully handle API errors.
• Async operations: Use async/await for better performance instead of blocking with .Result.
• Resource management: The CarsXE client implements IAsyncDisposable, so use await using or call DisposeAsync() when done.
• More info: For advanced usage and full details, visit the official API documentation.
