# Fetch Simple Application

`GET /simple/applications/{application_id}`

Fetch one application with its current variant, revision, and `data` merged.

The returned `data` includes the invocation `url`, the `parameters`
the revision was committed with, and the JSON `schemas` for inputs,
outputs, and parameters.

## Path parameters

- `application_id` string, uuid, required

## Response `200`

      - `agent_template_overlay` AgentTemplateOverlay — A documented subset of the `parameters.agent` authoring shape. Carries the platform-owned tools, authoring skills, and sandbox elevation the playground layers on top of the draft for the build kit. Entries are intentionally open (platform-op configs and `@ag.embed` references), so they are typed loosely: the full `parameters.agent` authoring template has no shared Pydantic model today (it rides as free-form `data.parameters`), and the SDK's runtime `AgentTemplate` is the flattened parse with different field names, so neither can be reused 1:1 to type this overlay.
        - `tools` object[] — Platform tool configs and `@ag.embed` tool references.
        - `skills` object[] — `@ag.embed` references to authoring skills.
        - `sandbox` object, nullable — Sandbox section overlay, e.g. `{permissions: {...}}`.
