typesafe-dotnet-sdk (mehdihadeli)

Community .NET SDK that sends state and named Noul, Choice and Score questions and deserializes answers into C# models.

Librarybeta

Overview

This community-maintained .NET SDK calls the System One API, deserializing answers into C# models with probabilities, choices, scores and model metadata. It targets .NET Standard 2.0 and .NET 10, defaults to Jev and can select other models available to your account.

The flow is to provide text or structured state, define named questions, send them in one request with SystemOneAsync, and apply your own thresholds. The README warns that the configured NuGet package ID, Typesafe.Sdk, is already taken by another community SDK, so for now you should use a project reference to this repository. It also reminds users that state is sent to the API and should not contain credentials or unnecessary personal data.
