WikiHere hover cards

Install one script. Normal links to public PoE2 WikiHere entity pages then show the same compact item facts used inside the wiki.

Add a normal link and the script

Keep the real WikiHere URL in the HTML. The link still works, remains indexable, and provides the backlink when JavaScript is unavailable.

<a href="https://poe2.wikihere.com/currency/chaos-orb">Chaos Orb</a>
<script async src="https://poe2.wikihere.com/embed/v1/hover-card.js"></script>

Working example

Point at the link, focus it with the keyboard, or tap it on a phone.

Chaos Orb

JSON endpoint

Version 1 returns the canonical URL, image, classification, properties, requirements, summary, modifier groups, flavour text, game version, and dataset identity.

Behavior and controls

Mouse: The card opens on hover and closes when the pointer leaves.
Keyboard: Focusing the link opens the card. Escape closes it.
Touch: The first tap opens the card. Tapping the same link again follows it.
Exclude a link: Add data-wikihere-preview="off" to that anchor.
Disable touch mode: Add data-touch="off" to the script element.

Content Security Policy

Allow https://poe2.wikihere.com in these directives:

script-src for the versioned loader
connect-src for preview JSON
style-src for the card stylesheet
img-src for locally cached entity images

Cache and request limits

Successful responses are cacheable for one hour and may be served stale while WikiHere refreshes them. The endpoint accepts 180 uncached requests per client in a one-minute window. The loader caches each preview for the lifetime of the page.
