Python API

from nz_house_prices import get_prices

# Get prices from all sites (parallel by default, ~20-25s)
prices = get_prices("123 Example Street, Ponsonby, Auckland")

for site, estimate in prices.items():
    if estimate.midpoint:
        print(f"{site}: ${estimate.midpoint:,.0f}")

# Use sequential mode if needed
prices = get_prices("123 Example Street, Auckland", parallel=False)

Context Manager (for multiple lookups)

from nz_house_prices import HousePriceScraper

with HousePriceScraper() as scraper:
    prices1 = scraper.scrape_address("123 Example Street, Ponsonby")
    prices2 = scraper.scrape_address("123 Main St, Auckland")

    for site, estimate in prices1.items():
        print(f"{site}: {estimate.midpoint}")

Features

• Parallel scraping - Queries all 5 sites concurrently (~20-25 seconds)
• Geocoding-based address matching - Accurately finds properties even when suburb names differ between sites
• Automatic address-to-URL resolution for all supported sites
• URL caching for faster repeated lookups
• Rate limiting to avoid overwhelming sites
• Retry logic with exponential backoff
• Both CLI and Python API interfaces

Requirements
