I deal a lot with APIs, it seems to me that the bigger the company it is the less they care about API docs. Would you pay for good, well written, updated docs? How much?
I believe <a href="https://readme.io" rel="nofollow">https://readme.io</a> is doing quite well, so I would venture to say, yes, people would pay over $59/mo for it. Is that what you mean? Or do you mean you would rewrite documentation for popular APIs so that they don’t suck?
