The API is not something new on Ghost, it appears for the first time in the version 0.7.2 but it still in beta with other features, this means is not complete yet, and we expect to see more endpoints in the future.
The APIs are helpful when you want to get or send information from different tools; it can be a website or a desktop application; we also can use it to get extra information from our blog.
To activate the API is easy you only need to go to the ghost console:
Then click on
Labs in the sidebar:
And finally, click on the Public API checkbox.
The API is documented in the Ghost developer guide.
