Frequently asked questions
Why would og:image fail even though the image exists?
The checker verifies the image URL is absolute (not relative) and reachable over HTTPS. A relative path or an image blocked from anonymous fetches will fail even if it renders fine in a logged-in browser.
Does this check Twitter Card tags too?
Yes — twitter:card and related tags are included, since most platforms fall back to Open Graph tags if Twitter-specific ones are missing.
Is there a limit on how many times I can call it?
10 per hour on a free account, 50 per hour on Free+ or paid — shared with the other check and QR tools, tracked per API key.
