Live preview
Pick a widget type:
Option 1 — one line (recommended)
Paste where you want the widget:
<div class="apicostcalc-widget"></div>
<script src="https://apicostcalc.com/widget.js"></script>
To choose a specific widget, add data-calc="token-cost" or data-calc="model-compare" to the div.
Option 2 — iframe
If your platform blocks external scripts:
<iframe src="https://apicostcalc.com/embed.html?calc=token-cost" width="400" height="520" style="border:0;max-width:100%" loading="lazy" title="AI cost calculator"></iframe>
The only rule
Free to use. The widget shows a small "Data by APICostCalc" link — keep it. That's the deal: you get a useful free tool, we get a bit of credit. No signup, no visitor tracking, nothing.
Works anywhere
WordPress (Custom HTML block), Ghost, Notion embeds, Webflow, plain HTML — anywhere you can paste code. Renders in light theme, scales to any width.
