What are some good city weather services on a commercial basis?

Question

API

Good afternoon, advise what are the professional services that provide weather data for a particular city, i.e. in XML or CSV, for a fee.
I tried to write to gismeteo, they can’t answer me for a week with their conditions and prices.
What else is good and more or less accurate?
