API Reference
Extract public Chrome Web Store extension metadata, search results, reviews, permissions, privacy details, categories, and charts as JSON. 12 endpoints documented below.

-H "x-api-key: $CRAWLORA_API_KEY"Google publishes no public API for reading the Chrome Web Store catalog, so extension data has to come off the store's own pages. Crawlora's 12 Chrome Web Store endpoints return search, listing, review, permission, privacy, chart, category, and publisher data as normalized JSON.
Search by keyword term, use the suggest endpoint for query completions, or browse a category, a curated collection, or a top chart.
The item endpoint takes the extension id; search cards already carry id, name, rating, user count, publisher, and detail URL.
Separate endpoints return an extension's declared permissions and its privacy disclosures — which is what makes extension-risk analysis possible without installing anything.
Every endpoint takes country and lang, so you can compare how a listing, chart, or category ranks across storefronts.
/chromewebstore/categoriesapiKey1 credit/requestReturns the reference taxonomy for the list endpoints: extension category groups and their subcategory slugs, the top-chart identifiers, and known curated collection slugs.
