Ask HN: Anyone making a living from a paid API?
Are there any solo devs or small teams out there genuinely paying their rent from selling API access? What's your API? How much MRR? What's your pricing model? How did you find your first paying customers? And most importantly - what problem are you solving that people will actually pay for monthly? Bonus points if you can share: - Your biggest challenge (rate limiting? customer support? competition?) - Whether you'd do it again - Any "I wish I knew this before starting" wisdom 2 comments on Hacker News.
