      Service Health Check
      Check whether the public GuGuData API service is reachable and returning the standard v1 response envelope.
      Method: GET
      Path: /healthcheck
      Demo: https://api.gugudata.io/healthcheck
      OpenAPI: https://gugudata.io/assets/openapi/gugudata.openapi.3.1.json
      Request Parameters:
      No request parameters.
      Response Fields:
      dataStatus (object, required): Response metadata returned by the current v1 contract.
      dataStatus.requestParameter (string, required): Normalized request parameters echoed by the service.
      dataStatus.statusCode (integer, required): Application-level status code returned by the current v1 contract.
      dataStatus.status (string, required): Application-level status enum returned by the current v1 contract.
      dataStatus.statusDescription (string, required): Application-level status message returned by the current v1 contract.
      dataStatus.responseDateTime (string, required): Response timestamp returned by the current service contract.
      dataStatus.dataTotalCount (integer, required): Total number of records that match the request.
      data (object, required): Health-check payload returned by the endpoint.
      HTTP Status Codes:
      200: Request processed successfully. Some endpoints expose a separate application-level status field in the response body, such as dataStatus.statusCode.
      500: Internal service error. Retry later or contact support if the error persists.
      503: Upstream service unavailable. Retry later; the requested upstream dependency is temporarily unavailable.
      Business Status Codes:
      The endpoint is primarily used for availability checks. Treat HTTP 200 with a valid dataStatus object as healthy.
      Key Features:
      Lightweight availability check for automated monitoring.
      Returns the standard response envelope used by the public API.
      Does not require an application key.
      Suitable for uptime probes and deployment smoke checks.
