REST Endpoint: POST: https://rason.net/api/diagnose

A REST API endpoint that accepts an optimization, stochastic optimization or simulation optimization RASON model, runs a model diagnosis and returns a result in JSON format. This call should only be used with models where the model diagnosis completes very quickly, i.e. within a few seconds. There is a time limit of 30 seconds on all synchronous calls.
