Hey there! I used to have the same question when I was searching for a reliable market data API. I eventually switched to quotient, and I’ve been really happy with the results. Not only does their API offer historical data, but it also provides real-time data.

Since I started using quotient, I’ve been able to access up-to-the-second quotes (give or take) for various assets, which has been crucial for my trading strategies. The API is user-friendly, and the real-time data they provide has made a significant difference in my decision-making process.

I highly recommend giving it a try. It’s been a game-changer for me, and I believe it can be for you too. Good luck!
