Configuration
Before using the colorbrightness API client, you have to setup your account and obtain your API Key.
You can get it by signing up at https://apiverve.com
Quick Start
Here's a simple example to get you started quickly:
using System;
using APIVerve;
class Program
{
static async Task Main(string[] args)
{
// Initialize the API client
var apiClient = new ColorBrightnessCalculatorAPIClient("[YOUR_API_KEY]");
var queryOptions = new ColorBrightnessCalculatorQueryOptions {
hex = "FF5733"
};
// Make the API call
try
{
var response = await apiClient.ExecuteAsync(queryOptions);
if (response.Error != null)
{
Console.WriteLine($"API Error: {response.Error}");
}
else
{
Console.WriteLine("Success!");
// Access response data using the strongly-typed ResponseObj properties
Console.WriteLine(Newtonsoft.Json.JsonConvert.SerializeObject(response, Newtonsoft.Json.Formatting.Indented));
}
}
catch (Exception ex)
{
Console.WriteLine($"Exception: {ex.Message}");
}
}
}
Usage
The APIVerve.API.ColorBrightnessCalculator API documentation is found here: https://docs.apiverve.com/ref/colorbrightness.
You can find parameters, example responses, and status codes documented here.
Setup
Authentication
APIVerve.API.ColorBrightnessCalculator API uses API Key-based authentication. When you create an instance of the API client, you can pass your API Key as a parameter.
// Create an instance of the API client
var apiClient = new ColorBrightnessCalculatorAPIClient("[YOUR_API_KEY]");
Usage Examples
Basic Usage (Async/Await Pattern - Recommended)
The modern async/await pattern provides the best performance and code readability:
using System;
using System.Threading.Tasks;
using APIVerve;
public class Example
{
public static async Task Main(string[] args)
{
var apiClient = new ColorBrightnessCalculatorAPIClient("[YOUR_API_KEY]");
var queryOptions = new ColorBrightnessCalculatorQueryOptions {
hex = "FF5733"
};
var response = await apiClient.ExecuteAsync(queryOptions);
if (response.Error != null)
{
Console.WriteLine($"Error: {response.Error}");
}
else
{
Console.WriteLine(Newtonsoft.Json.JsonConvert.SerializeObject(response, Newtonsoft.Json.Formatting.Indented));
}
}
}
Synchronous Usage
If you need to use synchronous code, you can use the Execute method:
using System;
using APIVerve;
public class Example
{
public static void Main(string[] args)
{
var apiClient = new ColorBrightnessCalculatorAPIClient("[YOUR_API_KEY]");
var queryOptions = new ColorBrightnessCalculatorQueryOptions {
hex = "FF5733"
};
var response = apiClient.Execute(queryOptions);
if (response.Error != null)
{
Console.WriteLine($"Error: {response.Error}");
}
else
{
Console.WriteLine(Newtonsoft.Json.JsonConvert.SerializeObject(response, Newtonsoft.Json.Formatting.Indented));
}
}
}
Error Handling
The API client provides comprehensive error handling. Here are some examples:
Handling API Errors
using System;
using System.Threading.Tasks;
using APIVerve;
public class Example
{
public static async Task Main(string[] args)
{
var apiClient = new ColorBrightnessCalculatorAPIClient("[YOUR_API_KEY]");
var queryOptions = new ColorBrightnessCalculatorQueryOptions {
hex = "FF5733"
};
try
{
var response = await apiClient.ExecuteAsync(queryOptions);
// Check for API-level errors
if (response.Error != null)
{
Console.WriteLine($"API Error: {response.Error}");
Console.WriteLine($"Status: {response.Status}");
return;
}
// Success - use the data
Console.WriteLine("Request successful!");
Console.WriteLine(Newtonsoft.Json.JsonConvert.SerializeObject(response, Newtonsoft.Json.Formatting.Indented));
}
catch (ArgumentException ex)
{
// Invalid API key or parameters
Console.WriteLine($"Invalid argument: {ex.Message}");
}
catch (System.Net.Http.HttpRequestException ex)
{
// Network or HTTP errors
Console.WriteLine($"Network error: {ex.Message}");
}
catch (Exception ex)
{
// Other errors
Console.WriteLine($"Unexpected error: {ex.Message}");
}
}
}
Comprehensive Error Handling with Retry Logic
using System;
using System.Threading.Tasks;
using APIVerve;
public class Example
{
public static async Task Main(string[] args)
{
var apiClient = new ColorBrightnessCalculatorAPIClient("[YOUR_API_KEY]");
// Configure retry behavior (max 3 retries)
apiClient.SetMaxRetries(3); // Retry up to 3 times (default: 0, max: 3)
apiClient.SetRetryDelay(2000); // Wait 2 seconds between retries
var queryOptions = new ColorBrightnessCalculatorQueryOptions {
hex = "FF5733"
};
try
{
var response = await apiClient.ExecuteAsync(queryOptions);
if (response.Error != null)
{
Console.WriteLine($"API Error: {response.Error}");
}
else
{
Console.WriteLine("Success!");
Console.WriteLine(Newtonsoft.Json.JsonConvert.SerializeObject(response, Newtonsoft.Json.Formatting.Indented));
}
}
catch (Exception ex)
{
Console.WriteLine($"Failed after retries: {ex.Message}");
}
}
}
Advanced Features
Custom Headers
Add custom headers to your requests:
var apiClient = new ColorBrightnessCalculatorAPIClient("[YOUR_API_KEY]");
// Add custom headers
apiClient.AddCustomHeader("X-Custom-Header", "custom-value");
apiClient.AddCustomHeader("X-Request-ID", Guid.NewGuid().ToString());
var queryOptions = new ColorBrightnessCalculatorQueryOptions {
hex = "FF5733"
};
var response = await apiClient.ExecuteAsync(queryOptions);
// Remove a header
apiClient.RemoveCustomHeader("X-Custom-Header");
// Clear all custom headers
apiClient.ClearCustomHeaders();
Request Logging
Enable logging for debugging:
var apiClient = new ColorBrightnessCalculatorAPIClient("[YOUR_API_KEY]", isDebug: true);
// Or use a custom logger
apiClient.SetLogger(message =>
{
Console.WriteLine($"[LOG] {DateTime.Now:yyyy-MM-dd HH:mm:ss} - {message}");
});
var queryOptions = new ColorBrightnessCalculatorQueryOptions {
hex = "FF5733"
};
var response = await apiClient.ExecuteAsync(queryOptions);
Retry Configuration
Customize retry behavior for failed requests:
var apiClient = new ColorBrightnessCalculatorAPIClient("[YOUR_API_KEY]");
// Set retry options
apiClient.SetMaxRetries(3); // Retry up to 3 times (default: 0, max: 3)
apiClient.SetRetryDelay(1500); // Wait 1.5 seconds between retries (default: 1000ms)
var queryOptions = new ColorBrightnessCalculatorQueryOptions {
hex = "FF5733"
};
var response = await apiClient.ExecuteAsync(queryOptions);
Dispose Pattern
The API client implements IDisposable for proper resource cleanup:
using (var apiClient = new ColorBrightnessCalculatorAPIClient("[YOUR_API_KEY]"))
{
var queryOptions = new ColorBrightnessCalculatorQueryOptions {
hex = "FF5733"
};
var response = await apiClient.ExecuteAsync(queryOptions);
Console.WriteLine(Newtonsoft.Json.JsonConvert.SerializeObject(response, Newtonsoft.Json.Formatting.Indented));
}
