openapi: 3.0.3 info: title: Ghost Content and Admin APIs Admin - Images Content - Tiers 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.' version: '5.0' contact: name: Ghost url: https://ghost.org license: name: MIT url: https://github.com/TryGhost/Ghost/blob/main/LICENSE servers: - url: https://{admin_domain}/ghost/api description: A Ghost site's API root (self-hosted or Ghost(Pro)) variables: admin_domain: default: demo.ghost.io description: The domain of the Ghost site (Ghost(Pro) uses *.ghost.io). security: - contentApiKey: [] - adminJwt: [] tags: - name: Content - Tiers description: Read-only public subscription tiers. paths: /content/tiers/: get: operationId: browseContentTiers tags: - Content - Tiers summary: Browse public subscription tiers parameters: - $ref: '#/components/parameters/ContentKey' - $ref: '#/components/parameters/Include' - $ref: '#/components/parameters/Filter' responses: '200': description: A list of public tiers with pricing. components: parameters: Filter: name: filter in: query required: false description: Ghost NQL filter expression. schema: type: string Include: name: include in: query required: false description: Comma-separated related data to include (for example authors,tags). schema: type: string ContentKey: name: key in: query required: true description: Content API key. schema: type: string securitySchemes: contentApiKey: type: apiKey in: query name: key description: Content API key from a Custom Integration, passed as the `key` query parameter.
