💡 Pro Tips

# 1. Use specific regions for best accuracy
ma-anpr test-api plate.jpg --region eup  # ✅ Better
ma-anpr test-api plate.jpg --region univ # ⚠️ OK but less accurate

# 2. Test different models to find best speed/accuracy balance
ma-anpr test-api plate.jpg --region eup --detector small_640p_fp32   # Faster
ma-anpr test-api plate.jpg --region eup --detector large_640p_fp32   # More accurate

# 3. Check remaining quota
ma-anpr test-api --check-quota

# 4. Get help
ma-anpr test-api --help

# 5. See all options
ma-anpr test-api --list-models

🔍 Troubleshooting

Rate limit exceeded?

# Wait until midnight UTC (resets daily)
# OR upgrade to paid license for unlimited requests

No plates detected?

# Try different detector models
ma-anpr test-api plate.jpg --region eup --detector large_640p_fp32

# Try universal region
ma-anpr test-api plate.jpg --region univ

Wrong text recognized?

# Make sure you're using correct region!
ma-anpr test-api plate.jpg --region kr   # For Korean plates
ma-anpr test-api plate.jpg --region eup  # For European plates

# Try larger OCR model
ma-anpr test-api plate.jpg --region eup --ocr large_fp32
