Python Library

from appstore_metadata_extractor import AppStoreScraper

# Initialize scraper
scraper = AppStoreScraper()

# Extract single app metadata
metadata = scraper.extract("https://apps.apple.com/us/app/example/id123456789")
print(f"App: {metadata.title}")
print(f"Version: {metadata.version}")
print(f"Rating: {metadata.rating}")

# Access In-App Purchases
if metadata.in_app_purchases:
    print(f"\nIn-App Purchases ({len(metadata.in_app_purchase_list)} items):")
    for iap in metadata.in_app_purchase_list:
        print(f"  - {iap['name']}: {iap['price']}")

# Access Support Links
print(f"\nSupport Links:")
print(f"  App Support: {metadata.app_support_url}")
print(f"  Privacy Policy: {metadata.privacy_policy_url}")
print(f"  Developer Website: {metadata.developer_website_url}")

# Extract multiple apps
urls = [
    "https://apps.apple.com/us/app/app1/id111111111",
    "https://apps.apple.com/us/app/app2/id222222222"
]
results = scraper.extract_batch(urls)

    # Extract multiple apps concurrently
    urls = ["url1", "url2", "url3"]
    results = await extractor.extract_batch(urls)

asyncio.run(main())

Advanced Usage

Custom Extraction Modes

from appstore_metadata_extractor import CombinedExtractor, ExtractionMode

extractor = CombinedExtractor()

# API-only mode (faster, less data)
result = await extractor.extract(url, mode=ExtractionMode.API_ONLY)

# Web scraping mode (slower, more complete)
result = await extractor.extract(url, mode=ExtractionMode.WEB_SCRAPE)

# Combined mode (default - best of both)
result = await extractor.extract(url, mode=ExtractionMode.COMBINED)

Rate Limiting Configuration

from appstore_metadata_extractor import RateLimiter

# Configure custom rate limits
rate_limiter = RateLimiter(
    calls_per_minute=20,  # iTunes API limit
    min_delay=1.0        # Minimum delay between calls
)

scraper = AppStoreScraper(rate_limiter=rate_limiter)

Caching

from appstore_metadata_extractor import CacheManager

# Configure cache
cache = CacheManager(
    ttl=300,  # Cache TTL in seconds
    max_size=1000  # Maximum cache entries
)

scraper = AppStoreScraper(cache_manager=cache)

Error Handling

The library provides robust error handling with automatic retries:

from appstore_metadata_extractor import AppNotFoundError, RateLimitError

try:
    metadata = scraper.extract(url)
except AppNotFoundError:
    print("App not found")
except RateLimitError:
    print("Rate limit exceeded, please wait")
except Exception as e:
    print(f"Extraction failed: {e}")
