Questions

BuiltWith API FAQ

The short answers. The docs have the long ones.

Still have a question? Talk to the people who build the endpoints.
Can I look up which technologies one website uses?

Not yet. Today the BuiltWith endpoints return the popular-technology list with live-site counts and the top-sites ranking.

Do I need a BuiltWith account or API key?

No. Upscrape reads BuiltWith's public pages; you only need your Upscrape API key.

What data can I get from BuiltWith?

Popular technology counts and top ranked sites. Each is its own endpoint with a published input schema, and the response is JSON.

How much does the BuiltWith API cost?

Every BuiltWith endpoint costs 1 credit per successful call. You buy credits once, with no subscription, and paid credits never expire. New accounts get free credits to try it.

Can an AI agent use the BuiltWith API?

Yes. Connect any MCP client to the Upscrape MCP server with OAuth or an API key. The agent finds the BuiltWith endpoint, checks its price and runs it with the same credits as the REST API.

Is it legal to scrape BuiltWith?

Upscrape reads public pages only and needs no login. How you use the data is yours to decide under the laws that apply to you; we sign a data processing agreement for your legal review.

What happens when BuiltWith changes its pages?

We fix the endpoint. Your request and the response fields stay the same.
