Source

Data is scraped from the public Chrome Web Store listing pages at:

https://chromewebstore.google.com/detail/{extensionId}

Metadata is extracted from the application/ld+json structured data block (JSON-LD, SoftwareApplication schema) embedded by Google for SEO purposes, supplemented by targeted regex probes for userCount, version, and updatedAt fields not present in the structured data. No authentication is required. Extensions that have been removed from the store return HTTP 404 and are skipped gracefully.
