The first documentation for the MCU Timeline API can be found at the link below. Currently the API is completely open and available for anyone that wants to check it out! There is currently no demo, since the project is entirely new. There are however a “snapshot” of the content that resides in the database that the API uses, which can be seen at https://snapshot.earth616.org/. The snapshot is just a part of the API, and by using the API there will be much more data to reach.
