Question regarding API for commercial purposes

I am looking for an API that provides cryptocurrency prices for a virtual crypto trading project for commercial purposes.
I came across Coinmarketcap and phased it out because it is very expensive and does not provide enough historical data.

Binance API seems great but I cannot find any pricing. Is Binance API really free?

All the endpoints on the API Documentation are public endpoints, although please take in attention the Limits associated.

If you want to directly download historical data, you can access to https://data.binance.vision/

Hello, can you confirm that despite of the Binance english terms [III.1.b.iv] we can provide commercial market analysis based on your public API if we respect the limits ?

We don’t have knowledge or manage the terms here, I would suggest to contact the Customer Support regarding that part for you to be 100% sure.
