print(f"{extension.name} - {extension.user_count:,} users, ★{extension.rating}")

# Or fetch by Chrome Web Store URL
url = "https://chrome.google.com/webstore/detail/google-translate/aapbdbdomjkkjkaonfhkkikfgjllcleb"

API Reference

ChromeWebStoreClient

The main client for interacting with the Chrome Web Store.

client = ChromeWebStoreClient(
    cache_ttl=3600,        # Cache duration in seconds (default: 1 hour)
    rate_limit_delay=1.0   # Delay between requests in seconds (default: 1 second)
)

Methods

• get_extension(extension_id: str) -> ExtensionMetadata: Fetch metadata for an extension
• get_extension_by_url(url: str) -> ExtensionMetadata: Fetch metadata from a Chrome Web Store URL
• search_extensions(query: str, max_results: int = 10) -> List[ExtensionMetadata]: Search for extensions (not yet implemented)

ExtensionMetadata

The data model containing all extension information.

@dataclass
class ExtensionMetadata:
    id: str
    name: Optional[str]
    description: Optional[str]
    version: Optional[str]
    developer: Optional[str]
    user_count: Optional[int]
    rating: Optional[float]
    # ... and many more fields

Examples

Get detailed information about an extension

from chrome_extension_info import ChromeWebStoreClient

client = ChromeWebStoreClient()

# Google Translate
extension = client.get_extension("aapbdbdomjkkjkaonfhkkikfgjllcleb")

print(f"Name: {extension.name}")
print(f"Version: {extension.version}")
print(f"Users: {extension.user_count:,}")
print(f"Rating: {extension.rating} ({extension.rating_count} reviews)")
print(f"Category: {extension.category}")
print(f"Last Updated: {extension.last_updated}")
print(f"Size: {extension.size}")

Cache behavior

# First call fetches from Chrome Web Store
extension1 = client.get_extension("extension-id")  # Network request

# Second call within cache TTL returns cached data
extension2 = client.get_extension("extension-id")  # From cache, no network request

Error handling

from chrome_extension_info import ChromeWebStoreClient, ExtensionNotFoundError, ChromeExtensionInfoError

client = ChromeWebStoreClient()

try:
    extension = client.get_extension("invalid-extension-id")
except ExtensionNotFoundError:
    print("Extension not found in Chrome Web Store")
except ChromeExtensionInfoError as e:
    print(f"An error occurred: {e}")

Exceptions

• ChromeExtensionInfoError: Base exception for all ChromePy errors
• ExtensionNotFoundError: Extension not found in the Chrome Web Store
• NetworkError: Network request failed
• RateLimitError: Rate limiting exceeded
• ParseError: Failed to parse response data
