    ## Authentication


    There is no standalone API-key auth — every request must be **signed**. An
    API key by itself authenticates nothing. Each call requires four headers
    together: `X-Api-Key` (your key), `X-Signature` (HMAC-SHA256 of `apiKey +
    timestamp` — or `apiKey + timestamp + userId` when `X-User-Id` is required —
    keyed with your API secret), `X-Timestamp` (unix seconds), and
    `X-Request-Id` (any unique string per request). The signature must be
    computed by a client script; there is no way to derive it by hand. Use the
    HMAC Generator flow to compute valid values for manual testing.


    ## Common Authentication Errors


    - **Invalid Client ID**: {"error_code":6092,"message":"X-Client-Id
    invalid","success":false}

    - **Invalid Secret**: {"error_code":6090,"message":"invalid
    secret","success":false}

    - **Timestamp (Older than 10 secs)**:
    {"errors":{"error_code":6093,"text":"timestamp expired"},"success":false}
