Any experience with RapidAPI marketplace?

Chiming in a few years later with a current data point: I listed a small funding-signals API there this year. Pros: real distribution, I get organic signups I wouldn't get otherwise, and their billing/quota handling means I don't have to build any of that myself. Cons: you're competing on a crowded results page so your listing title/description/example requests matter a lot for click-through, and the free-tier expectations on RapidAPI are pretty aggressive, plan your rate limits accordingly or you'll eat costs on users who were never going to convert. Net positive for me so far, but I'd treat it as one distribution channel among several rather than the growth plan.

Hey Daryl, did you tried to sell your api on RapidAPI eventually? Would be nice if you can share your experience :)

They have a great backend. The UI is a bit slow though. Their service is great and the range of features is really good and provides a lot of flexibility. I think it's the best API marketplace. Also as a user, it's great as it's simple to integrate APIs into your apps.
