Usage

from address_parser import AddressParser

# Load model
parser = AddressParser.from_pretrained("YOUR_USERNAME/indian-address-parser-model")

# Parse address
result = parser.parse("PLOT NO752 FIRST FLOOR, BLOCK H-3, NEW DELHI, 110041")

# Access structured output
print(result.house_number)  # "PLOT NO752"
print(result.floor)         # "FIRST FLOOR"
print(result.city)          # "NEW DELHI"
print(result.pincode)       # "110041"
