Check a page's meta tags and social preview
Paste a URL to see the title, description and Open Graph tags the page publishes, and roughly how its link card will look. Tags added by JavaScript are included, because the page is rendered before it is read.
The same capture from your code
With an API key it is one POST, in whatever language you already use. Replace YOUR_API_KEY with a key from the dashboard.

Questions
The page's title, its description, og:title, og:description and og:image, read from the page after its JavaScript has run. The description is the meta description, or og:description if that tag comes first in the page.
When the page declares a canonical link, that is what the row shows. When it does not, the row shows the address the page ended on after any redirects.
It shows the tags those networks read, not their exact layout. Each network crops the image and shortens the text in its own way.
It runs on the same capture API you would call with a key, so you can see exactly what a capture returns before you create an account. Every run is a real page load in a real Chromium browser.
3 runs an hour from each network, shared with the API playground. Viewports are between 320 and 1600 pixels wide, and full-page capture, PDF, cookies, headers and custom scripts are not available here. All free runs also draw on one shared monthly allowance, so the tool can occasionally be unavailable until it resets. A free account gets 100 credits a month of its own, and a basic capture costs 1.
The capture is not. The tool does not ask the API to save it, so the image and the Markdown come back to your browser in the response and are not kept. The request itself, including the URL you entered, is recorded in the request log like every API call.
Anything on a private or local network address is refused. Behind a login or a captcha, you get the login or verification page rather than the content. Captures leave from a single network address with no proxy rotation, so a site that blocks that address cannot be captured.
