Vibe Coding #2 - AI Agent for European Energy Data | ENTSO-E API with Python

Result

Ask “Where is Germany importing electricity from?” → instant cross-border flow data with AI.

The problem

ENTSO-E Transparency Platform has incredible data on European electricity markets
But accessing it requires understanding complex XML-based APIs
Navigating country codes and bidding zones
Parsing nested document structures and handling timezone conversions

The solution

Building MCP tools for ENTSO-E API:
