Script tag (recommended: resizes itself) Copy

```
<script async src="https://valuethen.com/embed.js" data-amount="100" data-from="USD" data-from-year="1970"></script>
```

Plain iframe (no JavaScript on your side) Copy

```
<iframe src="https://valuethen.com/embed/widget/?a=100&f=USD&t=USD&fy=1970" title="ValueThen inflation calculator" style="border:0;width:100%;max-width:100%;height:220px" loading="lazy"></iframe>
```

Works in any CMS that allows a script or iframe: WordPress, Substack (iframe), Ghost, Webflow, Notion (iframe). Several widgets on one page are fine.

## Terms

The widget is free for any site, commercial or not. The "Powered by ValueThen" link stays visible; that link is the price. Figures come from the same API as the site and refresh nightly. If you need the numbers without the widget, use the [API](https://valuethen.com/developers/).

## Use this page programmatically

The same figure from the free API, no key required:

```bash
curl "https://api.valuethen.com/v1/convert?amount=100&from=USD&to=EUR&fromYear=1970&toYear=2026"
```

```json
{ "result": 777.71, "method": "cpi-then-fx", "sources": ["World Bank FP.CPI.TOTL, 2010=100"] }
```
