Produce an Authorization header appropriate for nextstrain.org’s web API.
This is a development tool unnecessary for normal usage. It’s useful for
directly making API requests to nextstrain.org with
curl or similar
commands. For example:
curl -si https://nextstrain.org/whoami \ --header "Accept: application/json" \ --header @<(nextstrain authorization)
Exits with an error if no one is logged in.
usage: nextstrain authorization [-h]
