```

src/index.ts:542-579 (helper)

Shared helper function 'makeRequest' that constructs and sends signed HTTP requests to the AsterDEX Futures API using axios, handles errors, and returns JSON response.

const makeRequest = async (method: 'GET' | 'POST' | 'DELETE', path: string, params: any, isSigned = false) => {
  try {
    let config: any = {
      method,
      url: path,
    };

    if (isSigned) {
      if (!API_KEY || !API_SECRET) {
        throw new McpError(ErrorCode.InvalidRequest, 'API_KEY and API_SECRET must be configured.');
      }
      params.timestamp = Date.now();
      const queryString = new URLSearchParams(params).toString();
      const signature = crypto.createHmac('sha256', API_SECRET).update(queryString).digest('hex');
      params.signature = signature;
      
      config.headers = { 'X-MBX-APIKEY': API_KEY };
    }
    
    if (method === 'GET' || method === 'DELETE') {
      config.params = params;
    } else { // POST
      config.data = new URLSearchParams(params).toString();
      config.headers = { ...config.headers, 'Content-Type': 'application/x-www-form-urlencoded' };
    }

    const response = await this.axiosInstance.request(config);
    return { content: [{ type: 'text', text: JSON.stringify(response.data, null, 2) }] };
  } catch (error) {
    if (axios.isAxiosError(error)) {
      throw new McpError(
        ErrorCode.InternalError,
        `Aster API error: ${error.response?.data?.msg || error.message}`
      );
    }
    throw error;
  }
};
