POST /extract
unprobed
Give this API a web address and it will visit that page, then hand back everything an SEO professional needs to know: the page title, meta description, meta keywords, robots instructions, canonical link, H1/H2/H3 headings, how many links are on the page, and the HTTP status code. No setup required — just paste a URL and get structured data back in under two seconds.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
