What is an API?

An API (Application Program Interface) is the ability to connect to our software directly, without going through the user interface. Simply put, APIs allow users to submit some kind of input, perform an action, and return with a response.

Other industries have been taking advantage of APIs for quite some time. For example, flight comparison websites use APIs from a variety of flight providers to help you search for the best deal without having to visit each airline's website individually. SkyCiv API applies the same concept to the structural engineering context. With a single click, you can generate a model, run an analysis, design checks and respond with a simple pass/fail result, without the need for any visual or graphical user input.

APIs are driving our industry forward for faster and more efficient structural design.

Benefits of using an API

Analyze and design easier and faster

Say goodbye to repetitive and mundane tasks


Integrate with your current systems and applications to create a seamless workflows


API solutions can easily be modified and upgraded based on your needs and new technology


Build your own solutions that are specific to your company and needs - not relying on general use software.


Use a commercial product which has internal QA and testing processes

Future Proof

Access new features, products, design codes, and improvements at the time of release

All this, from a bit of code

The SkyCiv structural analysis and design API functions are easily implemented. Simply translate your data into the S3D model data (a simple JSON object) and unlock the possibilities for automated modelling, rendering, analysis and design functionality.

Use our Renderer, for Free*

Need to use our 3D renderer for your structure with screenshot and analytical result displays? We've got you covered. Simply embed a Javascript file, and you'll be able to leverage the full capabilities of our 3D web-based renderer. Make the most of the following features:

  • Display your structural model
  • Mouse interactions (create your own click actions)
  • Take screenshots and control view settings
  • Review results and display analytical results
  • Deflect and Deform your structure to review deflection

*Commercial solutions may require SkyCiv licensing.
