Request and response bodies come from the Go types the handlers send and decode. Where those types do not determine the shape (an interface, a map[string]any, an unknown custom encoding), the operation says so in `x-celum-schema-gap` instead of carrying a guessed schema. title: Celum API version: 1.0.0 servers: - description: Your Celum deployment url: https://{host} variables: host: default: celum.example.com description: The host your Celum backend is served from security: - sessionCookie: [] - bearerToken: [] tags: - description: AI assistant & MCP name: ai-assistant - description: Clusters & CAPI lifecycle name: capi - description: Certificates & external secrets name: certs - description: GitOps & apps name: gitops - description: IAM, audit & auth name: iam - description: Image library name: images - description: Infrastructure & supervisors name: infrastructure - description: Networking name: networking - description: Observability & platform health name: observability - description: Platform onboarding & settings name: platform-settings - description: Projects name: projects - description: Registries & mirroring name: registries - description: Security & flows name: security - description: Storage name: storage - description: Templates & addons name: templates - description: Virtualization platform (KubeVirt/CDI) name: virt - description: Virtual machines name: vms - description: Workloads & topology name: workloads paths: /api/supervisors/{name}/projects: post: tags: - projects summary: Create project description: >- Projects — group of namespaces / VMs / guest clusters with shared **Authorisation:** `project:Create` on `krn:celum:supervisor:{name}:project:*`. **Assistant tool:** `create_project` operationId: post_supervisors_byName_projects parameters: - description: >- The supervisor's name, as registered under Administration → Supervisors. in: path name: name required: true schema: type: string requestBody: content: application/json: schema: $ref: '#/components/schemas/api.projectCreateRequest.Input' required: true responses: '201': content: application/json: schema: $ref: '#/components/schemas/api.projectWriteResponse' description: Created.
