API
The tools on this site run in your browser and keep your data on your device. For automation, such as scripts, pipelines, and integrations, the same deterministic computations are available as a small HTTP API. It is the programmatic counterpart to the browser tools, not a replacement for them.
What this means for your data
The API receives only the input you send it, computes a result, and returns it. It is stateless and logs no query values or request bodies. If you need guaranteed zero data egress, use the browser tools, or run the open engine yourself.
The same engine as the browser
Every endpoint runs the same pure function the in-browser tool runs, so the API and the browser return byte-identical results.
