# Get a guest-published agent's cover image

> Returns the raw cover image bytes for a guest-published agent. The `Content-Type` is inferred from the file extension (`.png` → `image/png`, `.webp` → `image/webp`, otherwise `image/jpeg`). Cached for 5 minutes (`Cache-Control: public, max-age=300`). Returns 404 when the agent is not found, not guest-published, has no cover image, or the cover file is missing from S3. No authentication is required.

    REST endpoints of the IMP backend. GraphQL covers entity CRUD; REST covers
    agent runs, media, files, and system utilities. All requests require
    authentication unless the agent is public.

    description: >-
      LiteLLM tag-budget management for users, roles, teams, projects, agents,

  - name: Skills
    description: >-
      Skills are versioned bundles of files (markdown, scripts, assets) mounted
      into the agent sandbox. These endpoints manage the skill registry and
      individual skill files.
  - name: Uploads
    description: >-
      Uppy-compatible S3 companion routes for single-part and multipart file
      uploads. Accept the standard API key. The `internal-key` header (set to
      `INTERNAL_SECRET`) is accepted only on `/s3/delete`, `/s3/download`,
      `/s3/list`, and `/s3/object` — it does **not** work on `/s3/sign` or the
      `/s3/multipart` routes.
  - name: Compliance
    description: >-
      GDPR / DSGVO operator endpoints for data-subject access (export) and
      erasure. Both require `super_admin`.

    description: >-
      Shareable artifact links — create, list, and revoke share links for files
      stored in S3.
  - name: Credentials
    description: >-
      Tool-credential management — submit, list, and revoke per-user credentials
      for oauth and user_credentials-enabled tools. Values are stored encrypted
      and never returned through these endpoints.
  - name: Public Agents
    description: >-
      Unauthenticated endpoints for guest-published agent discovery. Only
      whitelisted metadata fields are ever returned; no instructions, tools, or
      model details are exposed.
