  title: Linode API v4 Account NodeBalancers API
  description: The Linode API v4 provides programmatic access to the full range of Akamai Connected Cloud (formerly Linode) products and services. It enables developers to create and manage compute instances, deploy Kubernetes clusters, configure NodeBalancers, manage DNS domains, provision Block Storage volumes, control Object Storage buckets, set up firewalls, and administer account settings. The RESTful API uses OAuth and personal access tokens for authentication and returns JSON responses, with support for filtering and sorting across all resource endpoints.
