Screenshot Examples · Example 3 of 3 in What to Capture

Render Your Own HTML

GEThttps://api.deepinfo.com/v1/lookup/screenshot

A capture of your own HTML (custom_html) without a url: redirected_url is about:blank.

Param: custom_html
Value: <h1>Hello from Deepinfo</h1><p>Rendered from custom_html.</p>

Asks for a capture of HTML sent in the request (custom_html), with no url.

The browser renders the given HTML instead of loading a page: the response has no url, redirected_url is about:blank and the file name starts with custom-html-. For long HTML, send it as a JSON body with Screenshot (POST).
