Common questions

Yes. The embed is two lines of standard HTML. It works anywhere you can paste custom code — WordPress, Webflow, Squarespace, Wix, Shopify, or a plain HTML file.
No. The calculator renders inside a Shadow DOM, which is a browser-native isolation layer. Your site's CSS cannot touch the widget's styles, and the widget's styles cannot touch your site.
No. You register your domain(s) in the dashboard. If a request comes from any other domain, it is blocked automatically — even if someone has your API key.
Verified June 2026 from primary sources: CareScout Cost of Care Survey, Amazon fee schedules (including the April 2026 fuel surcharge), Etsy Fees & Payments Policy, and verified POD supplier catalogs. We update data as platforms publish changes.
Your API key is deactivated immediately. The widget on your site will show "Calculator unavailable" until you resubscribe. You can reactivate anytime and the widget resumes instantly.
