# Management API

Base path: `http://localhost:8317/v0/management`

This API manages the CLI Proxy API’s runtime configuration and authentication files. All changes are persisted to the YAML config file and hot‑reloaded by the service.

Note: The following options cannot be modified via API and must be set in the config file (restart if needed):
- `allow-remote-management`
- `remote-management-key` (if plaintext is detected at startup, it is automatically bcrypt‑hashed and written back to the config)

## Authentication

- All requests (including localhost) must provide a valid management key.
- Remote access requires enabling remote management in the config: `allow-remote-management: true`.
- Provide the management key (in plaintext) via either:
  - `Authorization: Bearer <plaintext-key>`
  - `X-Management-Key: <plaintext-key>`

Additional notes:
- If `remote-management.secret-key` is empty, the entire Management API is disabled (all `/v0/management` routes return 404).
- For remote IPs, 5 consecutive authentication failures trigger a temporary ban (~30 minutes) before further attempts are allowed.

If a plaintext key is detected in the config at startup, it will be bcrypt‑hashed and written back to the config file automatically.

## Request/Response Conventions

- Content-Type: `application/json` (unless otherwise noted).
- Boolean/int/string updates: request body is `{ "value": <type> }`.
- Array PUT: either a raw array (e.g. `["a","b"]`) or `{ "items": [ ... ] }`.
- Array PATCH: supports `{ "old": "k1", "new": "k2" }` or `{ "index": 0, "value": "k2" }`.
- Object-array PATCH: supports matching by index or by key field (specified per endpoint).

      }
    }
    ```
  - Notes:
    - Statistics are recalculated for every request that reports token usage; data resets when the server restarts.
    - Hourly counters fold all days into the same hour bucket (`00`–`23`).
