## OpenAPI

````yaml /api-reference/local-api/openapi.yaml delete /modes/{id}
openapi: 3.0.3
info:
  title: HyperWhisper Local API
  description: >
    HTTP API exposed by HyperWhisper.app on `127.0.0.1` when the user enables

    Settings → API Server. Off by default. Used by MCP wrappers, benchmarking

    scripts, and power-user automation.


    **Port + token discovery.** The server writes

    `~/Library/Application Support/HyperWhisper/local-api.json`

    (chmod 600) on every start. Clients read that file to find the port

    and bearer token — neither value is hard-coded.


    **Response envelope.** Successful calls return `{"ok": true, ...}` with

    HTTP 200. Expected business failures (model not installed, missing API

    key, file not found, transcription engine errored, etc.) also return HTTP

    200 with `{"ok": false, "error": {"code": "...", "message": "...", "hint":
    "..."}}`.

    HTTP 4xx is reserved for protocol failures: malformed JSON (400), missing

    or invalid bearer token (401).
