API & Embedding

Embed Our Calculators

The simplest way to add CalcuZone calculators to your website is through an iframe embed. This requires no API key, no authentication, and works on any platform that supports HTML. Simply copy the code below and replace the URL with the calculator you want to embed:

<iframe
  src="https://calcuzone.eu/de/brutto-netto-rechner"
  width="100%"
  height="600"
  frameBorder="0"
></iframe>
<p style="font-size:12px;text-align:right;margin-top:4px">
  Powered by <a href="https://calcuzone.eu">CalcuZone.eu</a>
</p>

The embed is fully responsive and will adapt to the width of its container. You can set the heightattribute to match the calculator's content. Most calculators work well with a height between 500 and 800 pixels.

To embed a different calculator, simply change the URL path to match the calculator page on CalcuZone. For example, use /fr/simulateur-impot for the French tax simulator or /nl/bruto-netto-calculator for the Dutch salary calculator.

API Access

We are currently developing a REST API that will provide programmatic access to all CalcuZone calculator functions. The API will allow developers to send input parameters and receive calculated results in JSON format, making it easy to integrate financial calculations into your applications, dashboards, and workflows.

The API is currently in development and will launch in the coming months. If you are interested in early access, join the waitlist by contacting us at [email protected]. Early adopters will receive priority access and dedicated support during the beta period.

Usage Terms

Embedding CalcuZone calculators and using our upcoming API are subject to the following terms:

• Fair use: Embeds and API calls should be used for legitimate purposes. Automated high-volume requests that degrade service quality may be rate-limited.
• Attribution required: When embedding a calculator, the CalcuZone branding within the iframe must remain visible. Do not remove or obscure the CalcuZone name or links.
• No scraping: Automated scraping of calculator pages or results is not permitted. Use the official API for programmatic access once it becomes available.
• Commercial use: Free embedding is available for personal and editorial use. Commercial use at scale (such as integration into a paid product) requires a partnership agreement. See our Partnerships page for details.

Enterprise

For businesses and organizations that need custom API solutions, we offer enterprise plans with dedicated endpoints, higher rate limits, priority support, and custom calculator development. Enterprise API access includes SLA guarantees and can be tailored to your specific use case.
