APIVerve.API.TickerNews 1.2.3

Ticker News API

Ticker News is a stock news API that returns the latest news stories about one ticker symbol: US stocks and ETFs, stocks on 18 international markets, cryptocurrencies, futures and currency pairs. Each story comes with its headline, link, source, publisher and publication time, and is tagged as directly about the company or as a related market story. Paid plans add story summaries, headline tone and more stories per call.

This is a .NET wrapper for the Ticker News API

Quick Start

Here's a simple example to get you started quickly:

using System;
using APIVerve.API.TickerNews;

class Program
{
    static async Task Main(string[] args)
    {
        // Initialize the API client
        var apiClient = new TickerNewsAPIClient("[YOUR_API_KEY]");

        var queryOptions = new TickerNewsQueryOptions {
            Ticker = "AAPL",
            Market = "US",
            Relevance = "direct",
            Since = "2026-10-01"
        };

        // 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 Ticker News API documentation is found here: https://docs.apiverve.com/ref/tickernews. You can find parameters, example responses, and status codes documented here.

Setup

Authentication

Ticker News 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 TickerNewsAPIClient("[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.API.TickerNews;

public class Example
{
    public static async Task Main(string[] args)
    {
        var apiClient = new TickerNewsAPIClient("[YOUR_API_KEY]");

        var queryOptions = new TickerNewsQueryOptions {
            Ticker = "AAPL",
            Market = "US",
            Relevance = "direct",
            Since = "2026-10-01"
        };

        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.API.TickerNews;

public class Example
{
    public static void Main(string[] args)
    {
        var apiClient = new TickerNewsAPIClient("[YOUR_API_KEY]");

        var queryOptions = new TickerNewsQueryOptions {
            Ticker = "AAPL",
            Market = "US",
            Relevance = "direct",
            Since = "2026-10-01"
        };

        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.API.TickerNews;

public class Example
{
    public static async Task Main(string[] args)
    {
        var apiClient = new TickerNewsAPIClient("[YOUR_API_KEY]");

        var queryOptions = new TickerNewsQueryOptions {
            Ticker = "AAPL",
            Market = "US",
            Relevance = "direct",
            Since = "2026-10-01"
        };

        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.API.TickerNews;

public class Example
{
    public static async Task Main(string[] args)
    {
        var apiClient = new TickerNewsAPIClient("[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 TickerNewsQueryOptions {
            Ticker = "AAPL",
            Market = "US",
            Relevance = "direct",
            Since = "2026-10-01"
        };

        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 TickerNewsAPIClient("[YOUR_API_KEY]");

// Add custom headers
apiClient.AddCustomHeader("X-Custom-Header", "custom-value");
apiClient.AddCustomHeader("X-Request-ID", Guid.NewGuid().ToString());

var queryOptions = new TickerNewsQueryOptions {
    Ticker = "AAPL",
    Market = "US",
    Relevance = "direct",
    Since = "2026-10-01"
};

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 TickerNewsAPIClient("[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 TickerNewsQueryOptions {
    Ticker = "AAPL",
    Market = "US",
    Relevance = "direct",
    Since = "2026-10-01"
};

var response = await apiClient.ExecuteAsync(queryOptions);

Retry Configuration

Customize retry behavior for failed requests:

var apiClient = new TickerNewsAPIClient("[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 TickerNewsQueryOptions {
    Ticker = "AAPL",
    Market = "US",
    Relevance = "direct",
    Since = "2026-10-01"
};

var response = await apiClient.ExecuteAsync(queryOptions);

Dispose Pattern

The API client implements IDisposable for proper resource cleanup:

var queryOptions = new TickerNewsQueryOptions {
    Ticker = "AAPL",
    Market = "US",
    Relevance = "direct",
    Since = "2026-10-01"
};

using (var apiClient = new TickerNewsAPIClient("[YOUR_API_KEY]"))
{
    var response = await apiClient.ExecuteAsync(queryOptions);
    Console.WriteLine(Newtonsoft.Json.JsonConvert.SerializeObject(response, Newtonsoft.Json.Formatting.Indented));
}
// HttpClient is automatically disposed here
