FAQ
Is the crypto converter free?
Yes — free to embed with no sign-up and no API key. The only requirement is keeping the small attribution link back to Coinlib in the widget footer.
How do I add the crypto converter to my website?
Copy the embed code below into your site's HTML where you want the widget to appear. It works anywhere iframes are allowed, including WordPress, Wix, Squarespace and Blogger. For different coins, themes or sizes, use the configurator on the widgets page.
Does it update automatically?
Yes. Prices refresh automatically from Coinlib's live market data (synced roughly every 5 minutes), so the embed code never needs updating.
Will it slow my site down?
No — the widget loads in an iframe after your page renders, so it doesn't block your content, scripts or Core Web Vitals.
