The thread below is a mock forum. Each post embeds a single link in a different format. SuperHref scans every post on page load and cycles each link's badge through:
Checking… ✓ $12.99 ✗ Unavailable Error No ASIN 🔗 affiliate
For products that are unavailable or that can't be resolved, a carousel of replacements appears under the post. Watch the badges flip from Checking… to a result as the API responses come back.
Paste any Amazon or eBay product URL below and post it. The reply gets appended at the bottom of the thread and SuperHref scans it just like it would on a real forum.
Expected: ✗ No longer available + replacement carousel
This post demonstrates SuperHref's core value prop: an Amazon link to a product that has since been discontinued. The original Echo Dot 4th Generation is no longer on sale, so SuperHref surfaces a carousel of in-stock, top-rated alternatives right under the link — visitors keep converting instead of bouncing.
Expected: ✓ Available + product card
This post demonstrates the /dp/ASIN/ref=… URL — same /dp/
format as #1 but with Amazon's tracking suffix. The detector strips the
ref= portion before extracting the ASIN. Test link:
Atomic Habits.
Expected: ✗ No longer available + replacement carousel (GBP)
Same expired-link recovery, this time on a UK marketplace using the
older /gp/product/ URL format. The
Sony WH-1000XM4 on amazon.co.uk
is no longer on sale, so SuperHref pulls similar headphones from amazon.co.uk —
replacements automatically use the right marketplace and currency.
Expected: ✓ Available + product card (EUR price)
This post demonstrates an EU marketplace product on amazon.de — same
/dp/ASIN shape as US, different domain. Test link:
Echo Dot 4th Gen with Clock.
Expected: ✓ Available + product card
This post demonstrates a direct eBay item link in the
/itm/<slug>/<ID> format. Test link:
Nintendo Switch OLED.
Expected: ✓ Available + product card (GBP price)
This post demonstrates a UK eBay listing — same /itm/ format as #5 on a
different country domain. Test link:
Sony WH-1000XM5 on ebay.co.uk.
Expected: ✓ Available or ✗ Unavailable + replacement carousel
This post demonstrates a rover.ebay.com affiliate-redirect link with
the real listing URL embedded in ?mpre=. The detector decodes the
parameter to find the legacy item ID. Test link:
Atomic Habits via rover.ebay.com.
Expected: ✓ Available + product card
This post demonstrates the mobile-app URL format that Amazon's iOS share sheet
emits — /gp/aw/d/ASIN. Test link:
Atomic Habits via /gp/aw/d/.
Expected: ✓ Available + product card
This post demonstrates an Amazon search URL that carries the ASIN in the
?asin= query parameter. The detector pulls the ASIN out of the query
string. Test link:
Echo Dot via /s?asin=.
Expected: Checking… (longer than usual) → ✓ Available or Error if a.co is unreachable
This post demonstrates an a.co short link. The API has to fetch the
redirect server-side to resolve the underlying ASIN, so this request is slower than
a direct /dp/ URL. Test link:
a.co/d/05YCRQR.
Expected: Error badge — short link doesn't resolve
This post demonstrates how the detector handles a broken or fake short link. The URL below is a placeholder — it doesn't redirect to any real product, so the API fails to resolve an ASIN and the badge flips to Error. Test link: amzn.to/3example.
Expected: No ASIN badge, no rewrite
This post demonstrates a non-product Amazon URL — the homepage. There's no ASIN anywhere in the URL, so the detector tags it No ASIN and leaves the link alone. No API call is made. Test link: Amazon homepage.
Expected: No ASIN badge, no rewrite
This post demonstrates another non-product Amazon URL — the cart page. Same outcome as #12: No ASIN, link untouched. Test link: Amazon cart.
Expected: nothing — link ignored, no badge
This post demonstrates a URL that's not on Amazon or eBay at all. The detector doesn't even consider it; the link stays exactly as-is and no badge is added. Test link: Google search.
