I have an project where i implement live stock updates of various companies of all countries.

Can any one tell me where we can find "Free API" to fetch these details. I already search a lot on Google only found "Pro API". Need help :)

  • You can download from google easily enough still using an undocumented API. http://www.jarloo.com/real-time-google-stock-api/ – Kelly Aug 11 '16 at 00:49

    As a software developer, I would recommend [Alpha Vantage](http://www.alphavantage.co/). They offer free JSON APIs for realtime and historical stock quotes. [Here](http://www.alphavantage.co/query?function=TIME_SERIES_INTRADAY&symbol=MSFT&interval=1min&apikey=demo) is their realtime intraday data for MSFT. [Here](http://www.alphavantage.co/documentation/) is their full API documentation. You do need an API key, which can be obtained for free on their website. – Steve Carino Jun 17 '17 at 22:59

    While Alpha Vantage looks promising from a data point of view, it's pretty sketchy that they don't describe their business model or have an "About Us" page detailing company contact info, address, and information about the human beings who work there. I'd love to use their API, but they don't look too trustworthy to me. – jennEDVT Jul 03 '17 at 16:01
  • @SteveCarino is it realtime data or delayed data by 15mins? – Gaurav Dec 22 '19 at 16:45

Check the following they are free, they generate Json, though for different exchanges you need to ensure that correct syntax is used. even Yahoo finance works well, but it has some issues regarding NSE and BSE data, which is always generated Null

    You can use this as mentioned above http://nsetools.readthedocs.org/en/latest/index.html. If you want to have quotes of all companies, then you can use *get_stock_codes* API and then iterate over that. Implement threading to get you job done faster. – Vivek Jha Jan 07 '15 at 11:40

    Wasn't Google Finance API [deprecated](http://googlecode.blogspot.com.br/2011/05/spring-cleaning-for-some-of-our-apis.html)? – herrera Jul 12 '16 at 17:33
  • I use it in my application, works fine, and results are also up to date – Mrinal Kamboj Jul 12 '16 at 17:46

    Yahoo is no longer working for me. Google Finance was deprecated. But, I found a great replacement. They use standard REST APIs, return JSON, and their "sandbox" membership is free: https://developer.tradier.com/documentation – user225405 Nov 08 '17 at 23:28
