API

The Simplex API provides programmatic access to our structural engineering engines so you can automate calculations, integrate with your workflows, and build custom tools.

What you can do

Automate structural calculations
Integrate with CAD, spreadsheets, or internal apps
Run batch jobs and scripted workflows
Import/export engineering data programmatically

warning

Please avoid submitting large bursts of analyses or high-frequency polling. Our current fair‑use guideline is 200 API calls per month per account (subject to change). Exceeding this guidance may result in temporary throttling.
