  description: "# Changelog\n\n* 舊版 [v2 changelog](https://max-api.maicoin.com/doc/v2.html)\n\n* 2024-11-28\n  * 新增 GET /api/v3/deposit_address API\n\n* 2024-08-30\n  * 新版 API v3 釋出，請參考 API v3 列表。\n\n* 2026-08-15\n  * 新增 系統狀態 API，用於查詢 MAX API 目前的系統服務狀態。\n\n\n# 基本介紹\n\nMAX 交易所提供 RESTful API 接口，讓開發者能夠程式化與自動化地進行交易操作，以提升交易體驗。所有 API 請求與回應皆使用 JSON 格式。\n\n\n## API 類別\n| API 類別 | 身分驗證 | 流量限制 | 使用須知 |\n|----------|----------|-----------|----------|\n| 公開 API | 無需驗證 | 每個 IP 地址 1 分鐘最多 1200 請求 | 可直接使用 |\n| 私人 API | [需要驗證](https://campaign.maicoin.com/api-document) | 每個帳號每分鐘內最多 1200 個請求 | [需要申請 API 密鑰](https://max.maicoin.com/api_tokens) |\n\n# 身分驗證\n\n## API 密鑰申請\n在開始使用 API 前，您需要：\n\n1. [註冊 MAX 帳戶](https://max.maicoin.com/signup)（如果您還沒有帳戶）\n2. 完成身分驗證\n3. 前往 [API 密鑰管理頁面](https://max.maicoin.com/api_tokens) 申請 API 密鑰\n\n完成申請後，您會獲得：\n- Access Key：用於識別您的 API 請求\n- Secret Key：用於加密簽署您的請求\n\n請妥善保管您的 API 密鑰，不要洩露給他人。\n\n## API 認證方式\n使用私人 API 時，需要在 HTTP 請求中遵循以下步驟：\n\n### 認證步驟\n\n1. **準備必要的參數**\n   - 建立包含 nonce（通常是當前時間戳）的 object\n   - 添加其他必要的請求參數（如 market 等）\n\n2. **構建簽名內容**\n   - 將 object 與請求路徑合併（添加 path 字段）\n   - 將合併後的字典轉換為 JSON 字符串\n\n3. **生成 payload**\n   - 對 JSON 字符串進行 Base64 編碼\n\n4. **計算簽名**\n   - 使用 HMAC-SHA256 演算法\n   - 以 Secret Key 作為密鑰\n   - 對 payload 進行加密\n   - 將結果轉換為十六進制字符串\n\n5. **設置 request header **\n   - 在 HTTP request header 中加入以下資訊：\n\n| request header 名稱 | 說明 |\n|--------------|------|\n| X-MAX-ACCESSKEY | 您的 Access Key |\n| X-MAX-PAYLOAD | 根據請求內容生成的負載（payload） |\n| X-MAX-SIGNATURE | 使用您的 Secret Key 跟負載內容生成的簽名 (signature) |\n| X-Sub-Account | 指定要操作的子帳號，預設為主帳號 \"main\" |\n| Content-Type | application/json |\n\n6. **發送請求**\n   - GET：參數附加在 URL 上\n   - DELETE/POST/PUT：參數放在 request body 中\n\n## 認證程式碼範例\n\n負載是根據請求內容產生的字串，簽名則是根據負載所產生的雜湊值，以 JavaScript 為例\n\n### JavaScript\n\n```javascript\nimport { createHmac } from 'crypto';\nimport fetch from 'node-fetch';\nimport * as qs from 'qs';\n\nconst accessKey = '<Your Access Key>';\nconst secretKey = '<Your Secret Key>';\n\n/**\n * 發送 MAX API 請求的通用函數\n * @param {string} path - API 路徑\n * @param {string} method - HTTP 方法 (GET, POST, DELETE, PUT)\n * @param {Object} extraParams - 額外的請求參數\n * @returns {Promise<Object>} 響應數據\n */\nasync function makeRequest(path, method = 'GET', extraParams = {}) {\n  // 1. 準備必要的參數\n  const params = {\n    nonce: Date.now(),  // 毫秒級時間戳，需與伺服器時間差 30 秒內且不可重複\n    ...extraParams     // 添加其他必要參數\n  };\n\n  // 2. 構建簽名內容\n  const paramsToBeSigned = {\n    ...params,\n    path: path         // 將參數與路徑合併\n  };\n\n  // 3. 生成 payload\n  const payload = Buffer.from(JSON.stringify(paramsToBeSigned)).toString('base64');  // Base64 編碼\n\n  // 4. 計算簽名\n  const signature = createHmac('sha256', secretKey)  // 使用 Secret Key 作為密鑰\n    .update(payload)                                // 對 payload 進行簽名\n    .digest('hex');                                 // 轉換為十六進制字符串\n\n  // 5. 設置 request header\n  const headers = {\n    'X-MAX-ACCESSKEY': accessKey,      // 添加 Access Key\n    'X-MAX-PAYLOAD': payload,          // 添加 payload\n    'X-MAX-SIGNATURE': signature,      // 添加簽名\n    'Content-Type': 'application/json' // 設置內容類型\n  };\n\n  // 6. 發送\n  let url = `https://max-api.maicoin.com${path}`;\n  let options = {\n    method: method,\n    headers: headers\n  };\n\n  if (method === 'GET') {\n    // GET：參數附加在 URL 上\n    url += `?${qs.stringify(params, {arrayFormat: 'brackets'})}`;\n  } else {\n    // DELETE/POST/PUT：參數放在 request body 中\n    options.body = JSON.stringify(params);\n  }\n\n  const response = await fetch(url, options);\n  return await response.json();\n}\n\nasync function main() {\n  try {\n    // 請求 info (GET sample)\n    const info = await makeRequest('/api/v3/info');\n    console.log('Info response:', info);\n\n    // 請求取消訂單 (DELETE sample)\n    const orders = await makeRequest('/api/v3/order', 'DELETE', { id: xxxxxxx });\n    console.log('Cancel orders response:', orders);\n\n    // (POST sample)\n    // const createOrder = await makeRequest('/api/v3/wallet/spot/order', 'POST', { market: 'btcusdt', side: 'buy', volume: '0.001', price: '20000' });\n    // console.log('Create order response:', createOrder);\n  } catch (error) {\n    console.error('Error:', error);\n  }\n}\n\n// 執行主函數\nmain();\n\n```\n\n### Python\n\n```python\nimport base64\nimport hmac\nimport hashlib\nimport json\nimport time\nimport requests\nfrom urllib.parse import urlencode\n\naccess_key = '<Your Access Key>'\nsecret_key = '<Your Secret Key>'\n\ndef make_request(path, method='GET', extra_params=None):\n    \"\"\"\n    發送 MAX API 請求的通用函數\n    :param path: API 路徑\n    :param method: HTTP 方法 (GET, POST, DELETE, PUT)\n    :param extra_params: 額外的請求參數\n    :return: 響應數據\n    \"\"\"\n    #
