Polygon.io

Working with Polygon has been transformative, enabling us to finally display pricing data publicly, eliminate monthly reporting requirements, and significantly reduce costs.

Real-time stock and options data at the speed of the markets for our terminally online users

We integrated Polygon into our platform so anyone building LLMs or RAG models can connect to it and leverage the real-time and historic data of stocks.

I tryed it ALL, alpaca, finnhub, binance, yfinance, and so many more, but this one was the ONE. I really like it, i love the 29.99 plan that helps me build my app, if its not for Polygon, my app couldnt been runing. The api is really fast and i love the IA support that comes with it.

Polygon makes real time price easy, before them I had gone to at several real time price providers and since I'm a trader myself I find the best way to test my own stuff is to try to use it to trade and the only API that I thought was good enough for it was Polygon.
