Returns output data for completed tasks or error details for failed tasks. Available for tasks in any terminal status (completed, failed, cancelled). Accepts JWT Bearer, `sk-` integration credential, or `dk-` device credential. ## OpenAPI ````yaml /api-reference/core-openapi.yaml get /r/tasks/{taskId}/result openapi: 3.0.3 info: title: Cyberun API version: 1.0.0 description: > Multi-tenant GPU orchestration platform for enterprise private deployments. ## Authentication Two authentication families are supported: - **JWT Bearer** (`Authorization: Bearer `) — Used by team owners/admins/members for management endpoints and user sessions. JWT-authenticated requests that operate on a team **must** include the `X-Team-ID` header to select which team the request applies to (a user can belong to multiple teams). - **Credential Bearer** (`Authorization: Bearer `) — Unified machine credential. The credential is always scoped to a single team derived from the credential row, and any `X-Team-ID` header is **ignored**. The three kinds differ in identity and routing: | Kind | Prefix | Identity | Allowed surfaces | | ------------- | ------ | ------------------------- | --- | | `integration` | `sk-` | Team only | Runtime API (`/r/`) + the Web MCP endpoint. Rejected on every management endpoint because the authorization layer needs a user identity and `sk-` has none. | | `agent` | `ak-` | Team only | the platform's WebSocket handshake **only** — rejected by the REST surface at the middleware layer. | | `device` | `dk-` | Team + user (per-device) | Runtime API and scoped management endpoints — behaves like a JWT for the underlying user. Issued by the desktop pairing flow only (`POST /desktop/pair/confirm`). | the authorization layer runs against the user identity carried by JWT and `dk-`. `sk-` and `ak-` bypass the authorization layer; service-layer checks enforce team scope for them. Runtime endpoints under `/r/` accept **JWT (with `X-Team-ID`)**, `sk-`, and `dk-`. `ak-` is rejected at the middleware (it is only meaningful on the the platform's WebSocket handshake). Scoped management endpoints accept **JWT (with `X-Team-ID`)** or `dk-`; `sk-` is rejected on management because the the authorization layer authorize layer requires a user identity. The Web MCP endpoint accepts `sk-` only. Multipart upload endpoints (`/uploads/multipart/*`) remain JWT-only. Credential-bearing callers (`sk-`, `dk-`) should use single-part presign (`POST /r/files/presign`) instead — that returns a vanilla S3 PUT URL (≤ 5 GB by S3, subject to the server's configured request cap; default 500 MB). Files beyond the cap currently require the JWT-only multipart flow. ## Task Lifecycle Tasks follow this state machine: `pending → waiting → queued → running → completed | failed | cancelled`. Submit tasks via workflow run endpoints, poll status via GET /r/tasks/{taskId}, and retrieve results via GET /r/tasks/{taskId}/result. ## Pagination All list endpoints support pagination via `current_page` (default: 1) and `per_page` (default: 20, max: 100) query parameters. Responses include a `page_meta` object with `current_page`, `per_page`, and `total_count`. servers: - url: https://core.cyberun.cloud/api/v1 description: Cyberun Cloud API security: [] tags: - name: Auth description: > Authentication and account lifecycle: register, login, logout, token refresh, password reset, and email verification. - name: User description: | Current user profile management: view and update profile, change password. - name: Team description: > Team management: create, update, delete teams, leave, and transfer ownership.

DeviceAuth: type: http scheme: bearer description: > Device credential (Bearer dk-...) issued by the client device-pair flow (`POST /desktop/pair/confirm`). Carries the confirming user's identity, so it behaves like the user's JWT on team-scoped endpoints — the authorization layer runs against the user. Accepted on runtime + management endpoints. Never accepted on the platform's WebSocket. Team scope is bound at pair time; `X-Team-ID` is ignored. ApiKeyAuth: type: http scheme: bearer description: > Integration credential (Bearer sk-...). Team-scoped, no user identity, bypasses the authorization layer. Full runtime access on `/r/*` (including container invoke and proxy) and the Web MCP endpoint. **Not accepted on management endpoints** — those need a user-bearing credential (JWT or `DeviceAuth`). Team scope is taken from the credential; `X-Team-ID` is ignored. ````
