This is correct.

However, most people will not be able to trade at the XE quoted rates. Just try to go to your back and exchange. The price reported on CMP are what any random person can get, for real, using the crypto exchanges - without complicated paperwork. Without delay. With a separate bid and ask, instead of reporting a theoretical midpoint.

Also, the API is fully free. Anytime. Any volume of request. Commercial purposes included. No questions asked.

So yeah, that's currently smaller, but I think it is closer to what people and especially developers really care or need - the big fiat pairs, and true rates, without Terms-Of-Service.
