    The VMArea Public API lets you provision and manage VMs, networks,
    firewalls, SSH keys, backups, and webhooks programmatically. Authenticate
    every request with an API token (`x-api-key` header) created in the
    dashboard. Tokens carry coarse scopes (e.g. `vms:write`); endpoints reject
    calls that lack the scope they require.
