FastAPI array of JSON in Request Body for Machine Learning prediction

I’m working with FastAPI for Model inference in Machine Learning, so I need to have as inputs an array of JSON like this:

[  {"Id":"value","feature1":"value","feature2":"value","feature3":"value"  },  {"Id":"value","feature1":"value","feature2":"value","feature3":"value"  },  {"Id":"value","feature1":"value","feature2":"value","feature3":"value"  }]

The output (result of prediction) should look like this :

[  {"Id":"value","prediction":"value"  },  {"Id":"value","prediction":"value"  },  {"Id":"value","prediction":"value"  }]

How to implement this with FastAPI in Python?
