Connect to SerpApi Data from Blazor Apps

Blazor is a framework for developing modern, client-side web UIs using .NET technology. Instead of coding in JavaScript, developers can use the familiar C# language and .NET libraries to build app UIs.

The CData API Driver for ADO.NET can be used with standard ADO.NET interfaces, such as LINQ and Entity Framework, to interact with live SerpApi data. Since Blazor supports .NET Core, developers can use CData ADO.NET Providers in Blazor apps. In this article, we will guide you to build a simple Blazor app that talks to SerpApi using standard SQL queries.

Install the CData API Driver for ADO.NET

CData ADO.NET Providers allow users to access SerpApi just like they would access SQL Server, using simple SQL queries.

Install the SerpApi ADO.NET Data Provider from the CData website or from NuGet. Search NuGet for "SerpApi ADO.NET Data Provider."

Create a SerpApi-Connected Blazor App

Start by creating a Blazor project that references the CData API Driver for ADO.NET

1. Create a Blazor project on Visual Studio.

2. From the Solution Explorer, right click Dependencies, then click Add Project Reference.
3. In the Reference Manager, click the Browse button, and choose the .dll file of the installed ADO.NET Provider (e.g. System.Data.CData.API.dll, typically located at C:\Program Files\CData\CData API Driver for ADO.NET\lib etstandard2.0).

SELECT SerpApi Data from the Blazor App

1. Open the Index.razor file from the Project page.
2. In a APIConnection object, set the connection string:

   Start by setting the Profile connection property to the location of the SerpAPI Profile on disk (e.g. C:\profiles\SerpAPI.apip). Next, set the ProfileSettings connection property to the connection string for SerpAPI (see below).

   SerpAPI API Profile Settings

   SerpAPI uses API key authentication. To obtain an API key:

   1. Sign in to your SerpAPI account at https://serpapi.com
   2. Navigate to the API Key page at https://serpapi.com/manage-api-key
   3. Copy your private API key

   After obtaining your API key, set the following connection properties:

   • AuthScheme: Set this to APIKey.

   Set the following in the ProfileSettings connection property:

   • APIKey: Set this to your SerpAPI private API key.

   For example: Profile=C:\profiles\SerpAPI.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key_here';

3. The code below creates a simple Blazor app for displaying SerpApi data, using standard SQL to query SerpApi just like SQL Server.

         @page "/"
         @using System.Data;
         @using System.Data.CData.API;
         
         <h1>Hello, world!</h1>
         
         Welcome to your Data app.
         
         <div class="row">
             <div class="col-12">
         
                 @using (APIConnection connection = new APIConnection(
                   "Profile=C:\profiles\SerpAPI.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key_here';"))
                 {
                     var sql = "SELECT Asin, Title FROM AmazonSearch WHERE SearchQuery = 'mechanical keyboard'";
                     var results = new DataTable();
         
                     APIDataAdapter dataAdapter = new APIDataAdapter(sql, connection);
                     dataAdapter.Fill(results);
         
                     <table class="table table-bordered">
                         <thead class="thead-light">
                             <tr>
                                 @foreach (DataColumn item in results.Rows[0].Table.Columns)
                                 {
                                     <th scope="col">@item.ColumnName</th>
                                 }
                             </tr>
                         </thead>
                         <tbody>
                             @foreach (DataRow row in results.Rows)
                             {
                                 <tr>
                                     @foreach (var column in row.ItemArray)
                                     {
                                         <td>@column.ToString()</td>
                                     }
                                 </tr>
                             }
                         </tbody>
                     </table>
                 }
             </div>
         </div>
       

4. Rebuild and run the project. The ADO.NET Provider renders SerpApi data as an HTML table in the Blazor app.

   At this point, you have a SerpApi-connected Blazor app, capable of working with live SerpApi data just like you would work with a SQL Server instance. Download a free, 30-day trial and start working with live SerpApi data in your Blazor apps today.
