How far back does the Wayback Machine go?

The Wayback Machine has archived web pages since 1996. However, coverage varies significantly — major websites have captures going back 20+ years, while smaller or newer sites may have fewer or no captures. Use get_first_capture to find the earliest archived version of any URL.

Can I find captures that returned 404 errors?

Yes! Use get_captures_by_status with status_code="404". This returns all archived versions where the page returned a Not Found error. This is useful for tracking when pages were removed or URLs changed structure.

Can I discover all subdomains of a website that have been archived?

Yes! Use get_subdomain_captures with the base domain (e.g., "example.com"). This returns captures for all subdomains like www.example.com, blog.example.com, api.example.com, etc. It's useful for mapping the full archival footprint of an organization's web presence.
