https://sprites.dev/api has this command:
$ curl -X POST "https://api.sprites.dev/v1/sprites" \ -H "Authorization: Bearer $SPRITES_TOKEN" \ -d '{"name": "my-sprite"}'
which responds with
{"error":"name is required"}
if you use the request body in the full "Create Sprite" documentation at https://sprites.dev/api/sprites#create then it does work.
can I live with some rough edges for some personal workflows that only impact me when things break? sure. however, I was thinking about playing with some CI/CD stuff using sprites that would impact our whole team if things broke and I'm really on the fence because of this experience in the first 20 seconds.
Fly team - please put some black box probes or just better testing on the example you give in the quick start. if you document it, test it.
a "quick start" really should just work when you copy paste them.
