🌐 Frontend Integration

The backend provides a complete REST API that integrates seamlessly with modern frontend frameworks:

React/Vue.js Integration:

// Fetch energy data
const response = await fetch('/api/v1/energy/consumption?region=US48');
const energyData = await response.json();

// Trigger data pipeline
await fetch('/api/v1/pipeline/run-energy-ingestion', { method: 'POST' });

// Get quality dashboard
const qualityData = await fetch('/api/v1/quality/dashboard');
