      }
  
      const provider = getProvider();
      if (!provider) {
        return createErrorResponse("Provider is required to get logs, please set the provider URL");
      }
      const logs = await provider.getLogs(input.filter);
  
      return createSuccessResponse(
      `Logs retrieved successfully
        Logs: ${logs}
      `);
