Free plan: a link is required

If you show Card Prices data to people (a website, app, Discord bot, stream overlay or video) on the Free plan, show a visible link to Card Prices near the data or in your site's footer or credits.

Paid plans don't need to credit us. We appreciate it if you do.

What to use

On a web page, a plain HTML link. Point it at the page your data came from when you can, such as the card or set you're showing, or at the home page:

Prices by <a href="https://cardprices.io">Card Prices</a>

For one card:

<a href="https://cardprices.io/yugioh/card-info/Dark%20Magician">Dark Magician price</a> from Card Prices

Card pages live at https://cardprices.io/{game}/card-info/{card name}, with the name percent-encoded (encodeURIComponent in JavaScript), and set pages at https://cardprices.io/{game}/sets/{set name}.

Where you can't link (a Discord embed footer, a video, an app screen without links), write "Prices by Card Prices (cardprices.io)". In a Discord embed, put the link in the title URL or author URL.

Rules

• The link must be visible to the people who see the data, not hidden or display: none.
• Don't add rel="nofollow" to it.
• Don't imply Card Prices endorses your product.

No API key needed?

For a single card on a web page, the free price widget or card links may be all you need. Both are keyless and link back to Card Prices on their own.
