description = """

Nearly all endpoints require authentication, but guest authentication can be used.

API endpoints may change to add more features and properties, but we will attempt to keep it backwards-compatible.

We provide two API documentation viewers:

* [Redoc](/api/v2/): more comprehensive and clean *(default)*
* [Swagger](/api/v2/?swagger): less good, but has a built-in API client

We recommend reading the documentation using Redoc, and either using the Code examples provided next to each request,
or switching to swagger if you want an in-browser API client.
