    ## Authentication


    All endpoints require the `x-api-key` header (except `/health`, `/ready`,
    `/status`, `/metrics`).


    **Swagger UI**: Click the **Authorize** button (lock icon) at the top right,
    enter your API key, and click **Authorize**.


    ## Quick Start


    1. **List your accounts**: `GET /accounts`

    2. **Get live odds**: `GET /betslip?fixtureId=...&outcomeId=...&playerId=0`

    3. **Place an order**: `POST /place-orders`

    4. **Track results**: `GET /orders` or subscribe to WebSocket updates


    ## WebSocket


    Connect to `/ws` for real-time order, bet, and settlement updates.


    ```json

    {"type": "login", "apiKey": "your-api-key", "channels": []}

    ```


    Send an empty `channels` array to receive all updates. Available channels:
    `orders`, `bets`, `settlements`, `accounts`, `balance`, `betslip`,
    `fixtures`, `currencies`, `status`, `emergency`.


    Send `{"type": "ping"}` every 30 seconds to keep the connection alive.
