+# EPL Match Prediction API
+
+This API provides match predictions for English Premier League games using calibrated machine learning models.
+
+## Model Performance
+- **Overall Accuracy**: 75.0% (Random Forest)
+- **Confidence >70%**: 80.0% accuracy
+- **Confidence >75%**: 83.3% accuracy
+
+## API Endpoints
+
+### POST /predict
+Get match prediction for a specific game.
+
+Example request:
+```json
+{
+  "home_team": "Liverpool",
+  "away_team": "Man Utd",
+  "home_xg": 2.1,
+  "away_xg": 1.3
+}
+```
+
+### GET /health
+Check API status
+
+### GET /model-info
+Get model information and accuracy metrics
