So my lessons here after trying to tackle this market, it's hard. You can look at articles by Rapid and others that list "Top APIs". You can do some customer research by going to places like HN or reddit where people say, "I need an API for this". You can look at existing single purpose APIs in the market for niche use cases like currency conversion, IP data, etc. Or you can try build something and anticipate user needs based on your own. I built M3O.com for this purpose. Ultimately it was supposed to be a two sided market, where backend devs build for frontend devs, but never materialised that way.

I think either catering to your own first need is better than trying to build a thing you might not understand well. The alternative is to just do a poll on a large channel of distribution like a nocode platform where they're dying for a certain dataset.
