HTML Validator
Pricing
Pay per event
This actor validates HTML structure on web pages. It checks for DOCTYPE declaration, character encoding, language attribute, deprecated HTML elements, viewport meta tag, multiple head/body elements, excessive inline styles, and empty structural elements. Each page gets a validation score.
You can access the HTML Validator programmatically from your own applications by using the Apify API. You can also choose the language preference from below. To use the Apify API, you’ll need an Apify account and your API token, found in Integrations settings in Apify Console.
