SmartAPI getCandleData returns 403 rate-limit error despite being under documented limits

    API: getCandleData (Historical Data API)
    Error: 403 - "Access denied because of exceeding access rate"

    This error persists consistently across multiple hours, even for a single
    isolated API call with no other requests in between. My usage is nowhere
    near the documented limits (3 req/sec, 180/min, 5000/hour) — I tested with
    a single call after a 30+ second gap and it still fails, while login and
    the /market/v1/quote endpoint work perfectly.

    Client Code: D201112
    API Key app name: Stock Trader

    Could you please check server-side whether this API key/account is stuck
    in an incorrect rate-limit state?
