LinkPreview is the fetcher behind linkpreview.net, a JSON API that extracts title, description and image metadata from a URL so that customer applications can render link previews. It is operated by Interactive32 and requests are triggered on demand by API callers rather than by a scheduled crawl. This entry is matched with a pattern anchored to the start of the user agent, because other vendors ship agents that end in the same LinkPreview token. The operator documents the exact user agent string LinkPreview/1.6 (https://www.linkpreview.net) and states that the fetcher respects robots.txt, returning error 423 to the API caller when a page is disallowed. No IP ranges and no reverse DNS hostnames are published for verification.

How Centinel checks it

User agent: The request calls itself this crawler. Anyone can send the same string.

LinkPreview publishes nothing Centinel can check a source against, so a match reports the name and leaves the source unconfirmed. The match tokens, verification domains, and address feeds are not published here.

Allowing or blocking it

The crawler object in the /validate response sets access_allowed to true only for a verified source that your tenant allowlists. A policy rule can allow or block this crawler by its category, Preview.
