Great article! The alphavantage API is great (free!), but the data quality / accuracy needs some work. After trying out a few different APIs the Intrinio Stock API delivered the level of data quality I needed for pro-work at a pretty decent price. They have a 30-day free trial for many of their feeds. Their standardized US Fundamentals feed is excellent for quant work as well.
