# Get an evaluation



## OpenAPI

````yaml /api-reference/openapi.json get /api/v1/evaluations/{id}
openapi: 3.1.0
info:
  title: SimForge Cloud API
  version: '2026-10-24'
  description: >-
    The public SimForge API: what `simforge --cloud`, `simforge login` and the
    Python client call. Authenticate with a bearer token: the access token
    `simforge login` stores, an AI agent's access token (its recipe is
    `/auth.md`), or an `sfk_` API key. A `/api/v1` 401 carries
    `WWW-Authenticate: Bearer
    resource_metadata="<host>/.well-known/oauth-protected-resource"`. `/api/v1`
    errors are an `ErrorEnvelope`; `/api/cli` and `/agent` errors are an OAuth
    error object.


    Versions: send `SimForge-Version: <date>` (2026-10-01, 2026-10-21,
    2026-10-22, 2026-10-23, 2026-10-24) and every `/api/v1` response is in that
    version's shape and names it in the same header; this document describes
    2026-10-24. A request without the header gets 2026-10-01, where an error's
    hint is `detail.hint` and `GET /api/v1/evaluations` names its rows `jobs`. A
    header that is not a date, or a date before 2026-10-01, is `400
    bad_request`. Every response also carries `SimForge-Cli-Minimum`: the oldest
    `simforge` CLI the server serves.


    Retries: from 2026-10-21, send a new `Idempotency-Key` (1-255 characters)
    with every POST, PUT, PATCH and DELETE, and the same key when retrying that
    request. The first request's answer is kept for 24 hours and a repeat gets
    it again with `Idempotent-Replayed: true`; the key with any other request,
    or while the first is still running, is `409 idempotency_conflict`
    (`retryable` while running). A 5xx answer is not kept. Creating an API key
    refuses a key (its secret is shown once).
