The extension economy is opaque until you can query it like a catalog. This API returns listing details across 18 categories so you can rank by installs, compare pricing models, or watch new entrants.
What you get
Extension title, description snippets, ratings, user counts, developer info, pricing, and category tags — the fields you would otherwise scrape from store pages one URL at a time.
Example request
curl "https://data-apis.elormdokosi.com/chrome-webstore/extensions?category=productivity&limit=5"Swap category and limit to page through niches (ad blockers, dev tools, AI assistants, etc.).
When to use it
- Extension market analysis — size a category before you build.
- Competitor research — track rating and install deltas for named rivals.
- Developer insights — see who publishes across multiple properties.
Playground
Test calls in the Lab playground or see /apis/chrome-webstore for all routes.
