Infinitum Selection Tools API

An HTTP/JSON API over Infinitum's Motor Selection Tool (MST) and Fan Selection Tool (FST), documented by Infinitum for third-party integration with BMS, design software and internal tools. Infinitum's own support article names three endpoints in limited release - a fan selection endpoint (inputs airflow CFM and static pressure, returns matching fan systems as JSON), a motor selection endpoint (returns matching motor configurations as JSON) and a fan chart endpoint (returns a base64 JPEG performance chart) - and points at MST API documentation at https://mst.goinfinitum.com/docs/api. That reference 307-redirects to a sign-in, endpoint URLs and credentials are issued on request, and Infinitum states that detailed API documentation requires a valid NDA and a commercial agreement. No baseURL is recorded here because Infinitum does not publish one.
