原文外掛簡介
A discount of “40 % off” means nothing if the crossed-out price was never real. This plugin answers a different question: is this price good compared with what the product usually costs?
Paste an ASIN, an amazon.de link or an amzly.de product link, and you get a compact badge with a coloured dot and a plain rating — “Günstiger als sonst”, “Normaler Preis”, “Derzeit teurer”. The rating comes from the price history collected by amzly.de, not from Amazon’s own crossed-out prices.
How it looks
The badge is a neutral pill that sits inside your text without breaking the line height. The signal colour lives in the dot alone, so it never fights your theme:
Green — very cheap right now, or an all-time low
Blue — cheaper than usual
Orange — normal price
Red — currently pricier, better to wait
Grey — not enough price history yet
Built to stay out of the way
Server-side rendering. Your visitors’ browsers never contact amzly.de. No consent banner needed for the badges.
Light and dark, automatically. Follows each visitor’s system setting through pure CSS, so it works even on a fully cached page. You can force one mode if your theme needs it.
Nothing loads on pages without a badge. No CSS, no JavaScript.
Respects reduced motion. Visitors who ask for less animation never see the pulsing dot.
Never a broken post. If the API is unreachable, badges keep showing the last known price instead of disappearing.
Where the badge links to
Always to the product page on amzly.de, never straight to Amazon. That is deliberate: a plugin must not place someone else’s affiliate tag into your posts.
Click statistics
Optional and switched on by default: the plugin counts clicks on your badges so you can see which ones actually get used. Stored per click are the date, the post and the ASIN — no IP address, no cookie, no user agent, nothing that identifies a visitor. Entries older than a year are deleted automatically. Switch it off and the front end loads no JavaScript at all.
Ways to insert a badge
One block named Amzly: pick badge, price history, list, two-product comparison or a comparison table in the block settings, with a live preview that checks the product really exists
The shortcode [amzly asin="B09X7CRKRZ"]
Shortcode options: link, theme, size, variant, logo, label, price, delta, pulse, target
Only amazon.de
Links to amazon.com, amazon.co.uk and other marketplaces are rejected on purpose. The price data is amazon.de in euros — a badge on a link to another country would claim a price that does not apply there.
External services
This plugin uses two external services. One is required, the other is only reached for one specific kind of link.
1. amzly.de (required)
The plugin relies on the public API of amzly.de for price data and price ratings. Without it the plugin cannot work: it is the sole source of the price history the badge is based on. The service is operated by the author of this plugin.
What is sent, and when
When you insert a badge in the editor, and when a page containing a badge is rendered with an expired cache, your web server requests https://amzly.de/api/v1/asins or https://amzly.de/api/v1/asin/{asin}.
Sent are: the ASIN of the product, the IP address of your web server (unavoidable in any HTTP request) and your site address in the user agent, in the form AmzlyPriceBadge/1.0.1; https://example.com.
No visitor data is sent. Badges are rendered on your server; your visitors’ browsers never contact amzly.de. Only when a visitor actually clicks a badge does their browser follow the link, exactly like any other outgoing link.
Responses are cached, by default for six hours, so a page with badges normally causes no request at all.
Optional, and off unless you switch it on
If you enable “Report clicks to amzly.de” in the settings, the plugin sends once a day to https://amzly.de/api/v1/badge/report: your domain, the date, and a click count per ASIN. Never anything about individual visitors.

2. Amazon (only for short links)
Amazon short links such as https://amzn.to/3XYZabc do not contain the product number. To find out which product one points at, the plugin has to ask Amazon where the link leads.
What is sent, and when
Only when you enter an amzn.to or amzn.eu link, and only at that moment — in the editor, or once when a post containing such a link is first rendered. Every other kind of input (a product number, an amazon.de link, an amzly.de link) is resolved locally and sends nothing.
Your web server makes a single HEAD request to the short link and reads the address it redirects to. Sent are: the short link itself, the IP address of your web server and your site address in the user agent. No page content and nothing about your visitors.
The result is cached, so the same short link is resolved once and not again.
You can avoid this service entirely by using product numbers or full amazon.de links instead of short links.
