Use the Wolfram Alpha API

[langningchen]

Microsoft Math Solver will be retired on July 7, 2025 ¹ , but the Math Assistant in OneNote is still alive. Using the new OneNote Math Assistant will make this project alive. According to some basic detection, the new API uses the domain edumathsolver.microsoft.com, but further research is needed to understand the details of the API and whether it has authentication.

The API uses /api/MathSolver/PostSteps, but it needs authentication using the HTTP header Authorization

The Request Body is like
