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="/.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: ` (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). license: name: Apache-2.0 identifier: Apache-2.0 servers: - url: https://dev.simforge.ai description: Development (dev.simforge.ai) security: [] tags: - name: Sign-in description: >- `simforge login`: OAuth 2.0 device and browser sign-in for the CLI, the session behind a token.
