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 & 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 moved, e.g. around company news which is also available from the Polygon stock data 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.
