Ask HN: What are the best Marketing APIs today?

(Disclaimer: I work for Mashape). I found 2 marketing- related APIs when I searched for "marketing" in Mashape

- https://www.mashape.com/crosspollinate/crosspollinate-conten...

- https://www.mashape.com/amartin/ubersuggest

Moz, Twitter, Facebook Graph API, SEMRush, and Topsy.

I have never heard of a Marketing API. What do you mean?
