All endpoints in this document are scoped to your organization. They are the same APIs powering the Barndoor portal under **LLM Configuration**, **LLM Controls**, and **Settings - My Models**, exposed for teams that prefer scripting over the UI. ## Base URL All requests are issued against your Barndoor instance: ``` https://app.barndoor.ai/api/llm-gateway ``` Replace `app.barndoor.ai` with your tenant host if you run on Enterprise. ## Authentication Endpoints accept a JWT Bearer token issued by your Barndoor identity provider. Tokens can be obtained interactively via the Barndoor SDK: ```ts const sdk = await loginInteractive(); ``` The token must be sent in the `Authorization` header on every request: ``` Authorization: Bearer eyJhbGciOi... ``` Note: the `bd-...` API keys you create through these endpoints are for runtime LLM traffic (`/v1/chat/completions`, `/v1/messages`, etc.), not for administrative calls. Administrative endpoints require a user/admin JWT. ## Permissions Most endpoints require an `admin` (or higher) role on the calling user. Read-only endpoints are typically accessible by all authenticated users. Read-only listings under `/user/...` are scoped to the authenticated user. ## Errors Errors are returned as JSON with a stable shape: ```json { "error": "BadRequest", "message": "request_timeout_secs must be between 1 and 3600" } ``` contact: name: Barndoor Support url: https://barndoor.ai servers: - url: https://{host}/api/llm-gateway description: >- Production / Trial (Barndoor SaaS).
