Overview

The Figviz API turns plain-text descriptions into clean, labeled science and math diagrams. It is the same generation engine that powers the Figviz web app, exposed as a single REST endpoint so you can build diagram creation into your own product, worksheet pipeline, or LMS integration.

Who this is for

Teams that need diagrams produced at scale without a designer in the loop: edtech platforms generating per-lesson visuals, publishers building figure sets, and internal tools that turn a teacher's prompt into a printable image.

Three steps to your first image

1. Sign up at figviz.com and add a pay-as-you-go credit pack.
2. Open Settings > API and mint a key. It is shown once and starts with fvk_.
3. Send a POST to /api/v1/generate. The full contract is in the API Reference.
