My attempt at documenting the un-documented Bandcamp.com web API. Unfortunately they even removed documentation for the previously documented endpoints. Today's devs pages only cover high level APIs, none dealing with the actual content.
Thanks to the Internet Archive we can still find an old copy of the legacy Bandcamp API.
The API definition is stored as JSON and YAML files in Open API v3.0 format in the data folder. Use eg. the swagger.io editor to import and edit, or other swagger.io tools to process the files.
Check out the interactive API documentation.
