RASON runs on your own machine — the client starts it, so there is no endpoint to ping. 80 installs a week from npm.
Build, solve, and analyze RASON optimization, simulation, data science, and decision models
Nothing serious here today
Today is the operative word: we check RASON every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

<RASON_BEARER_TOKEN> (RASON API bearer token. Required for model management, solving, and diagnostics. Obtain at https://rason.com/).
The author’s registry entry marks it as required.
Optional settings from the registry entry, left out of the block above:
RASON_SERVER_URL (Base URL of the RASON REST API. /api is appended automatically), RASON_RESULT_ARRAY_LIMIT (Maximum array/dataFrame rows before solver results are summarized), RASON_RESULT_SIZE_LIMIT (Maximum solve-result size (in characters) before truncation), RASON_REQUEST_TIMEOUT (HTTP request timeout in milliseconds).
