When working with Alpha Vantage APIs:

Data Format: Prefer CSV over JSON when both formats are available
- CSV is more compact and easier to parse for tabular data
- Use
```
datatype=csv
```
  parameter in API requests
Response Handling: Always write API responses to files first
- Save responses to temporary or data files before processing
- Read from files with appropriate limits to avoid context burden
- Example: Use Read tool with
```
limit
```
  parameter to control data size

使用Alpha Vantage API时：

数据格式：当同时提供CSV和JSON格式时，优先选择CSV
- CSV格式更紧凑，更易于解析表格数据
- 在API请求中使用
```
datatype=csv
```
  参数
响应处理：始终先将API响应写入文件
- 在处理前将响应保存到临时文件或数据文件中
- 读取文件时设置适当的限制，避免上下文过载
- 示例：使用Read工具并配合
```
limit
```
  参数控制数据大小
