I don't understand down votes.

I often will see the price of an API (cough Google maps) and roll my own solution.

An independent developer capable of making a replacement for the entire Google maps API on their own probably isn’t likely to remain poor for long.

Creating an API isn't that hard. Crafting system architecture to handle a reasonable amount of load isn't that hard nowadays either.

But where the heck am I supposed to get all the data?

That’s exactly my point. Making a full replacement for an API (endpoint) is much more than writing some swagger.

openstreetmap in this example!
