    Have you looked at Alpaca's Market Data API or Polygon.io. Both premium options are reasonably priced and give you access to both historical and real time trades. Source: over 1 year ago

    Https://alpaca.markets/data - As you see you get 100% market coverage for all US exchanges and unlimited API / WebSocket access.

  • The use of API on a web app, considered individual or commercial use?
    I am building a web app, and I would like to use the polygon.io API on the back-end to forecast the market sentiment. The individual upgrade is $200, while business upgrade would cost $2000. Would my use of the API considered personal or commercial? Source: 5 months ago
  • ChatGPT is going to revolutionize the stock market (with data)
    It's worth mentioning that we use polygon.io to provide market information, which has the ability to specify time frames for data. Each ChatGPT call will have the appropriate information at the time it should. We also use a temperature of 0, as we want idempotent predictions. Source: 10 months ago
  • Good data provider
    I am currently testing the products from Polygon.io . They seem to have everything I need, however I noticed that sometimes prices are not adjusted for splits. I have seen on subreddit that this is a known problem with Polygon (about more than 3 years ago!) so I am wondering about the quality of their data. Source: 10 months ago
