Hint: Equinix Metal's API can be reached at

Most of the endpoints in the API require authentication. Authenticating is done with an authentication token in the X-Auth-Token header.

curl -H 'X-Auth-Token: my_authentication_token'

Authentication tokens are used to identify the user your application is connecting to the API on behalf of. Think of authentication tokens as permanent sessions—the user creates authentication tokens, and your app can use them to connect to the API on their behalf until they delete the token.

Users can create authentication tokens in the Equinix Metal Portal.
