I prefer to write them by hand. Most APIs, to start, don't have a lot to them. They tend to grow in scope over time. So, it's pretty easy to just throw together your initial idea, and incrementally grow it from there. I might think differently if confronted with a huge API surface area to build off the bat, but I haven't run into that yet.
