💻 Quickstart (Python)

1. Download Model from HuggingFace

from huggingface_hub import hf_hub_download
import joblib

# Download model weights
model_path = hf_hub_download(repo_id="alixansec/urlaz", filename="urlaz_phishing_detector.joblib")
model = joblib.load(model_path)

2. Predict URL

# Pass 35 structural features extracted from URL (see predict_url.py)
probability = model.predict_proba([features])[0][1]

if probability >= 0.95:
    print("🔴 PHISHING DETECTED")
else:
    print("🟢 SAFE")
