For site owners and ranked providers
Embed ChainChoice
Show a published figure on your site, with its date and its source beside it. Every snippet below draws from the same files as the pages, so it says what they say.
Lowest fee for €500 of Bitcoin in Germany
One line from the bitcoin page for Germany: the lowest published fee for that purchase, with the date the fee was read and its source. It is the page's own head row, recomputed with every deploy. The spread is not measured, and the embed says so. No script, font, cookie or tracker, and no "Visit" button.
As a frame (360 × 120)
Paste both lines. The second is a plain link in your own page, outside the frame: keep it, and word it as you like.

For a provider's own site: its current rank in one ranking, drawn from the same file as the ranking page. Add ?format=json to the image address for the facts and the snippet.
oEmbed
Paste a ranking address into any oEmbed consumer (a CMS, a forum, a newsletter tool) and it fetches the top-three embed itself.

- Rank and score come from the published order and move with it: a badge or an embed always shows today's place, never the place on the day it was pasted.
- When a product leaves a ranking, its badge stops answering (404) instead of showing a stale claim.
- Free. Nothing is for sale: no provider can buy a badge, a position or a better wording.
- Embedding a badge or a widget never touches a rank. The order is computed without reading who embeds, who links or who pays.
- The same badge, the same snippet and the same rules for every ranked product, whether or not ChainChoice has an affiliate agreement with it.
- Use the image as served (hotlinked, unaltered), and keep its link to the ranking it came from.
What is counted
Each time a page shows a badge or an embed, its site's host name (sent by the browser as the referrer origin, never the page path) is counted for the month, so we know where ChainChoice appears. Visits through a snippet carry utm_source=embed or utm_source=badge and your host name. No cookie is set and nothing about the reader is stored.
