AlphaVantage.Net

The most popular .Net client library for Alpha Vantage API.

Release notes for version 2:

• Most of the library classes were rewritten from scratch, keeping in mind all issues that were opened for the previous release.
• New client works with System.Text.Json under the hood which is faster than classic Newtonsoft Json
• Now you can create client's instances with 6 different constructors. It gives you access to underlying HttpClient + allow you to create wrappers around it if needed.
• All packages were written using newest C# Nullable reference types feature, to reduce possible bugs

Packages:

• AlphaVantage.Net.Core - low-level client for Alpha Vantage API based on HttpClient and System.Text.Json

Fully typed clients:

• AlphaVantage.Net.Stocks - stock time series.
• AlphaVantage.Net.Forex - Forex data
• AlphaVantage.Net.Crypto - cryptocurrencies data
• AlphaVantage.Net.TechnicalIndicators - technical indicators time series.
