Download Polygon Market Data
The Polygon Data API provides programmatic access to Polygon’s financial data with historical data back to 15+ years ago for a variety of stock market, news articles & financial data types.
While the data is not real time, the data available from Polygon downloads can be invaluable for building machine learning models in finance, backtesting models, and understanding how historical markets have moved in the past, e.g. around company news which is also available from the Polygon stock data API.

Download CSV Files from Polygon API
Our service makes it easy to perform bulk data exports of the Polygon Data API without having to write any code. This will help you generate custom CSV files for historical data you need using the Polygon API, allowing for precision queries so you’re not overwhelmed with irrelevant historical financial data you don’t need and will just clog up your machine learning and analysis models.
Check out some of the API endpoint scraping integrations on this page to get started and see what kind of data you can download for the financial sectors and companies you’re interested in. Links to the individual endpoints will appear when you’re logged in to our service (which is free to try), and you can then experiment with accessing the various API endpoints to extract out Polygon financial data.
