Not them, but copyright law is something everyone trying to distribute content should be aware of(especially if you want to redistribute content that you didn't generate).

I'm not a lawyer, but from my understanding as long as you're not actually sending the logo image data through your paid API(e.x. if you just link to the logo file on the MasterCard/airbnb/etc. server instead of hosting it on your own) you should be ok.
