What is NestAPI?

NestAPI is a hosted nesting engine you call over HTTPS. Send it the parts you need to cut and the sheets (stock material) you have, and it returns an optimised layout that packs the parts onto the sheets with minimal waste — ready to drive a laser, plasma, waterjet, router, or punch. It is built for teams who want production-grade nesting inside their own product without building and maintaining a nesting engine themselves:
  • CAD/CAM and MES vendors embedding nesting in their software
  • Sheet-metal, joinery, glass, and composites fabricators automating job preparation
  • Quoting and estimating tools that need fast material-usage figures

​
What you can do

Nest from DXF

Submit base64-encoded DXF files and receive a packed layout.

Nest from geometry

Submit encoded or parametric geometry instead of files.

Quote nesting

Get fast material-usage estimates for quoting.

1D / linear nesting

Optimise cuts of bar, tube, and profile stock.

Webhook results

Receive results asynchronously when a nest completes.

How it works, in one minute

  1. Authenticate with an API key (Authorization: Bearer <key>).
  2. Submit a nesting request — files or geometry, plus your sheets and settings.
  3. The API returns a RequestId immediately; nesting runs asynchronously.
  4. Receive the result at your webhook URL, or stream progress over SignalR.
  5. Fetch exports (DXF, reports, and more) for the completed nest.
Nesting is asynchronous by design — real layouts can take seconds to minutes. You never hold a request open waiting; you get a RequestId and the result is delivered when ready. See the nesting workflow.
