How to Scrape Walmart with C#

Walmart contains valuable data — product listings, prices, ratings, review counts, and more. Scraping this data directly means dealing with anti-bot detection, CAPTCHAs, IP rotation, and constantly breaking selectors. The Scavio API handles all of that and returns clean, structured JSON from a single POST request.

This tutorial shows you how to scrape Walmart using C# and the Scavio API. By the end, you will have a working C# script that fetches real-time Walmart data and parses the results.

Prerequisites

• C# installed on your machine
• A Scavio API key (free tier includes 500 credits/month — no credit card required)

Step 1: Install Dependencies

Install HttpClient to make HTTP requests:

dotnet new console
dotnet add package System.Text.Json

Step 2: Make Your First Walmart Search

Send a POST request to the Scavio Walmart API endpoint with your query. The API returns structured JSON with product listings, prices, ratings, and more.

using System.Net.Http.Json;
using System.Text.Json;

var apiKey = "your_scavio_api_key";
var client = new HttpClient();
client.DefaultRequestHeaders.Add("x-api-key", apiKey);

var response = await client.PostAsJsonAsync(
    "https://api.scavio.dev/api/v1/walmart/search",
    new { query }
);

var json = await response.Content.ReadAsStringAsync();
var data = JsonSerializer.Deserialize<JsonElement>(json);
Console.WriteLine(JsonSerializer.Serialize(data, new JsonSerializerOptions { WriteIndented = true }));

Step 3: Example Response

The API returns structured JSON. Here is an example response for a Walmart search:

{
  "search_metadata": { "status": "success" },
  "products": [
    {
      "position": 1,
      "title": "FlexiSpot E7 Standing Desk",
      "product_id": "1234567890",
      "price": "$349.99",
      "rating": 4.5,
      "reviews_count": 1823,
      "fulfillment": "Free delivery",
      "pickup": "Available for pickup"
    }
  ]
}

Every field is structured and typed — no HTML parsing, no CSS selectors, no regex extraction. Your C# code can access any field directly.

Step 4: Full Working Example

Here is a complete, runnable C# script that searches Walmart and prints the results:

using System.Net.Http.Json;
using System.Text.Json;

/// <summary>
/// Scrape Walmart search results using Scavio API.
/// Run with: dotnet run
/// </summary>

var apiKey = Environment.GetEnvironmentVariable("SCAVIO_API_KEY")!;
var client = new HttpClient();
client.DefaultRequestHeaders.Add("x-api-key", apiKey);

async Task<JsonElement> SearchWalmart(string query)
{
    var response = await client.PostAsJsonAsync(
        "https://api.scavio.dev/api/v1/walmart/search",
        new { query }
    );
    response.EnsureSuccessStatusCode();
    var json = await response.Content.ReadAsStringAsync();
    return JsonSerializer.Deserialize<JsonElement>(json);
}

var results = await SearchWalmart("standing desk");
Console.WriteLine(JsonSerializer.Serialize(results, new JsonSerializerOptions { WriteIndented = true }));

Why Use Scavio Instead of Scraping Walmart Directly?

• No proxy management. Direct scraping requires rotating proxies to avoid IP bans. Scavio handles all of this server-side.
• No CAPTCHA solving. Walmart aggressively blocks automated requests. Scavio returns clean data every time.
• Structured JSON output. No HTML parsing or CSS selector maintenance. Get typed, consistent data from every request.
• Multi-platform in one API. Search Google, Amazon, YouTube, and Walmart from the same API key with the same authentication pattern.
• Free tier included. 500 credits/month with no credit card required. Each search costs 1 credit.
