If you want to take a look of a project that works with AJAX processing against the API you can take a look at https://github.com/Tornevall/mcu-timeline-api. The project is live and running under the side https://snapshot.earth616.org/

What is the MCU Timeline API?
This is the place to look for updates regarding the MCU timeline API, which currently is a regular document at this site here. Below is links to documents on how to use the new open API for the MCU Timeline view.
In each resource, there are clickable links directly to examples that can be used. Since the old MCU documents page is growing very quickly and is about to be very hard to maintain, this page is the first part of a replacement for that project. Instead of having just this page, we're building it as an auto updating API.
This API is continuously updated with new features!
