usage_description="
Queries the given Spotify API endpoint

Requires \$SPOTIFY_ACCESS_TOKEN in the environment, or \$SPOTIFY_ID and \$SPOTIFY_SECRET, in which case it'll call spotify_access_token.sh to generate a new token for the duration of this script

If accessing API endpoints for private user data that require authorized tokens, such as /v1/me/... , then you'll need to export SPOTIFY_PRIVATE=1 before generating a token with interactive authorization pop-up due to quirks in the Spotify API

For efficiency to avoid regenerating API tokens for every script call, do the following once an hour in your shell:

export SPOTIFY_ACCESS_TOKEN=\"\$('$srcdir/spotify_api_token.sh')\"

Generate an App client ID and secret here and add a callback URL of 'http://localhost:12345/callback':

API documentation for calls to make:

https://developer.spotify.com/documentation/web-api/reference/

Eg.

spotify_api.sh /v1/users/harisekhon

SPOTIFY_PRIVATE=1 spotify_api.sh /v1/me/tracks

Used by adjacent spotify_*.sh scripts for more serious usage
