CORS Limitations

Note that some of the eToro API endpoints have CORS restrictions and should be called from a server-side environment. The tools in this server handle these requests on the server side to avoid CORS issues.

Usage Example

The server exposes a REST API for accessing these tools, which can be called from any HTTP client:

GET /tools                          # List all available tools
GET /tools/:name/schema             # Get tool schema
POST /tools/:name/execute           # Execute a tool

Example of using the fetch_etoro_portfolio tool:

curl -X POST http://localhost:3000/tools/fetch_etoro_portfolio/execute \
  -H "Content-Type: application/json" \
  -d '{"username": "yoniasia"}'
