Launch Library 2, by The Space Devs, is a detailed database of past and upcoming rocket launches, providers, pads, and related events. Query upcoming launches to get status, timing windows, launch provider, and rocket details as JSON. It's keyless, but anonymous requests are throttled to a low rate.
