# Option 1: Add to .env file in running directory
echo "ALPHAVANTAGE_API_KEY=your_api_key_here" >> .env

# Option 2: Export as environment variable

Usage Guidelines for Agents

When working with Alpha Vantage APIs:

1. 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

2. 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

Structure

• references/ - All API documentation organized by category
• references/index.md - Full tree view of all available APIs
