Ghost Admin - Images API

  title: Ghost Content and Admin APIs Admin - Images API
  description: 'Ghost is an open-source (MIT) publishing platform for professional publications, newsletters, memberships, and paid subscriptions. Every Ghost site - whether self-hosted or on managed Ghost(Pro) - exposes two documented public REST APIs under https://{admin_domain}/ghost/api/.


    The Content API is read-only and is authenticated with a Content API key passed as the `key` query parameter; it serves published posts, pages, authors, tags, tiers, and public settings for consumption by front-ends and static sites.


    The Admin API is read-write and is authenticated with an Admin API key that is used to sign a short-lived JWT sent as `Authorization: Ghost {token}` (a staff access token or user session may also be used). It manages posts, pages, members, tags, labels, tiers, offers, newsletters, users, images, themes, and webhooks.


    The `{admin_domain}` server variable is the site''s domain (for Ghost(Pro), typically a `*.ghost.io` domain). All requests must use HTTPS. The `Accept-Version` header (for example `v5.0`) declares the minimum compatible API version.'
