Types

FastAPI uses pydantic extensively. Default parameter types are string without type hints.

This will use int.

@app.get('/shapes/{shape_id}')
async def get_shapes(shape_id: int):
    for shape in shapes:
        if shape['id'] == shape_id:
            return shape

404 for not found

@app.get('/shapes/{shape_id}')
async def get_shapes(shape_id: int):
    for shape in shapes:
        if shape['id'] == shape_id:
            return shape

    raise HTTPException(status_code=404, detail=f"Shape with id {shape_id} not found")
