How do you interrupt a loop in a ModuleScript?

I have a module script function that moves an AI using pathfinding using a custom method like so (modscript:MoveToPoint()). Its goal is to behave as the humanoid:MoveTo function but using pathfinding. However, one of the benefits of the MoveTo is that it can be interrupted by another call. How can I do this with the module script? (How can I interrupt a loop in a module script from the script that calls it?)

Outside code:

pathfinder:MoveToPoint(unit.HumanoidRootPart.Position, resource.PrimaryPart.Position + Vector3.new(0,20,0),0.16,1, unit)

Module Script Code:

function API:MoveToPoint(startPosition,endPosition,ratio,startIndex,model)
    --pathfinder was changed to API
    local torso = model.Torso

    local childs = model:GetChildren()
    for i = 1,#childs do
        if childs[i].ClassName == "Humanoid" then
            humanoid = childs[i]
        end
    end

         path = API:FindPath(startPosition, endPosition)
                points = path:GetPointCoordinates()
                index  = path:CheckOcclusionAsync(startIndex)
                API:SetEmptyCutoff(ratio)

--          for pointnumber,pvector3 in pairs(points) do
--              part = Instance.new("Part")
--              part.Parent = Workspace             
--              part.Anchored = true
--              part.CanCollide = false
--              part.Size = Vector3.new(1,1,1)
--              part.CFrame = CFrame.new(pvector3)
--              part.Name = "PathfindingPart"
--          end             

            for pointnumber,pvector3 in pairs(points) do
                --print(pointnumber)
                --print(pvector3)
                    if pvector3.y > torso.Position.y + 1 and ((pvector3.y - torso.Position.y) > 5) then   --        if point.y > mytorso.Position.y or ((point.y - mytorso.Position.y) > 5) then
                        humanoid.Jump = true
                        humanoid:MoveTo(pvector3)   
                    end 
                humanoid:MoveTo(pvector3)
            repeat
                humanoid:MoveTo(pvector3)
                local distance = (torso.Position - pvector3).magnitude
                wait()
            until distance < 4
            end
end
