Web scraping for agents. Point it at a URL and it returns the page as clean markdown, JavaScript-rendered pages included.

Search the web and read full pages, extract fields with a JSON schema you define (validated, never invented), read a store's catalogue or a blog's posts from the platform's own feed, and check whether a page has changed. Failed requests cost nothing. The free plan includes 1,500 credits a month.
