Yahoo Finance API is over — long live New Finance APIs!

The Yahoo Finance API has long been a reliable tool for many of the data-driven investors. Many have relied on their real-time data-flow and have built neat trading applications. Tragically, one day Yahoo decided to discontinue their service and slapped a hefty price-tag on getting data from them.


Luckily, the world has not stopped, and there are great new APIs which can give you top-notch financial data (mostly) for free!

Let’s see the 6 alternative finance APIs:

Alpha Vantage

What happens when you bring together a community of researchers, developers, and business analysts? A free finance API, with real-time and historical data about stocks, forex (FX), digital assets. They have huge support from third-party developers, and different integrations are available on GitHub from enthusiastic supporters. Fans have been impressed with its ease of use, the variety of functions and data, and the quality of service- all of which is free!

Learn how to use these Finance APIs to make informed investment decisions

World Trading Data

This is a great database collecting financial prices from all over the world. World Trading Data offers both historical and real-time info, with intraday updates from minute-by-minute to hourly refreshing. They also offer updates on currency prices. It has been praised for the reliability and variety of their service. Their basic package is free, but if you need more data, you might need to sign up for a paid plan.


400,000 customers can’t be wrong- Quandl is a top-notch data source for financial and economic analysis. Their datasets are used by top hedge funds, asset managers, and investment banks. They provide core financial data and alternative datasets for institutional clients. One of the key advantages of Quandl is that they present information in different forms, so the analyst can choose what works best for them without the need to spend time transforming datasets. Anonymous API users have 20 calls per 10 minutes or 50 calls per day. Signing up means 300 calls per 10 seconds, 2,000 calls per 10 minutes and a limit of 50,000 calls per day.

Through one simple API, Intrinio offers 300+ data feeds, with its backend using machine learning and AI algorithms to sort through and clean data. Most of the trial sets are available for free, but then you pay for what you use- by getting charged for each feed you download. The API might be different from the original Yahoo version, though there is a ton of documentation to get the setup right.

EOD Historical Data

EOD provides real-time and historical data from the stock, mutual fund, and ETF market, pulling together an impressive 500 million data points. They cover 60+ stock exchanges, 120,000 symbols, 120+ cryptocurrencies and 50+ FOREX pairs. Talk about selection!

For tests, you can get free API access, but for more data, they require a monthly subscription starting from $9.99 a month.


For those who are more tech-savvy, IEX provides a great option to get market data. IEX is a small, but fast-growing index, providing a new specialized look at the volatile, dark, and out-of-reach market for the average trader. IEX was created in response to questionable trading practices that had become widely used across traditional public Wall Street exchanges, as well as dark pools and other alternative trading systems. IEX levels the playing field with transparency in a straightforward manner. See more about them here!

He graduated with a BA in Political Science from Tulane University in 2016. Fluent in English and proficient in Mandarin and Spanish, he can communicate and connect with most of the world’s population too, and this certainly helped John as he gained work experience interning for the U.S.-Taiwan Business counsel in Washington D.C. as an investment analyst and then working alongside U.S. Senator Robert P. Casey of Pennsylvania as a legislative intern. He subsequently worked as a business analyst for a mutual fund in Singapore, where his passion for travel and aptitude for creating connections between opportunities and ideas was the perfect intersection of natural ability and experience, spending his time travelling between Cambodia, Hong Kong, and China investigating and discovering untapped investment opportunities. John is a fund manager for OCIM’s fintech fund, and currently progressing towards becoming a CFA charter holder. He loves to travel for business and pleasure, having visited 38 countries (including North Korea); he represents the new breed of global citizen for the 21st century.


  1. You should also add SimFin ( to the list, they offer (in my opinion) the best free API for company fundamentals and share prices (although they don’t have intraday prices).
    Their premium subscription that offers unlimited API calls is also by far the cheapest anywhere at USD 20/month.

  2. At Leeway dot tech we offer an API for price and fundamental stock data with history at very affordable prices. Documentation can be found at the data API page. Contact us any time via E-Mail in case of questions.
