Chrome Extension Details - Fetch Emails, Phones, Websites and Full Metadata from Any Chrome Extension

Give it an extension ID or a full Chrome Web Store URL and it returns everything the store knows. Name, version, star rating, user count, full description, manifest JSON, icon URLs, file size, supported languages, last updated date, and full developer contact info including email, phone number, address, and company name. No browser, no HTML scraping. It talks directly to the store's own internal API.

Use cases

• Research competing extensions: compare user counts, ratings, and what permissions they request
• Track version bumps and install growth over time for extensions you care about
• Audit permissions and host access by inspecting raw manifest JSON
• Collect developer emails, phone numbers, and addresses from store listings for outreach
• Build a Chrome Web Store dataset for analysis, sales prospecting, or research

FAQ

Can I pass full Chrome Web Store URLs instead of bare extension IDs? Yes. Full URLs like https://chromewebstore.google.com/detail/merciapp-ai-writing-assis/gccahjgcckaemgpliioopngfgdaceffo and bare IDs like gccahjgcckaemgpliioopngfgdaceffo both work.

Does this actor scrape the page or call an API? It calls the store's internal batchexecute API. Faster than page scraping and returns clean structured data, including the raw manifest JSON.

What happens if an extension ID is invalid or not found? It logs the error and keeps going. The failed ID shows up in the dataset with an errorMessage field instead of extension data.

How many extensions can I run at once? The default cap is 1000 per run. For larger lists, batch them using Apify's scheduling.

Does the manifest field have the full manifest? Yes. The complete parsed manifest.json including permissions, content scripts, background workers, and host permissions.
