The title is misleading. In none of the listed projects do you "get paid". I often do "glue things together with APIs" types of projects (you could argue that all software is basically that) using modern cloud services which make it relatively easy. But doing anything takes several days and therefore costs a couple thousand dollars - the activation energy for a project. I'll always do the projects where a client is willing to pay that activation energy before doing something which is "speculative". Having said that, I think the idea of doing something like "Upwork" but with client aggregation and monthly pricing is a great idea - but still speculative, so a great idea for somebody else to pursue.
