How to short-circuit a pipeline using Option.none?

I am trying to make an effect which gets a resource from an HTTP endpoint. Successful status codes are

200

200 and

404

404. In the case of

404

404, I want to short-circuit a pipeline and return

Option.none()

Option.none()

Option.none()

Option.none(). In the case of

200

200 I want to grab the JSON and decode it, then wrap it in

Option.some()

Option.some()

Option.some()

Option.some(). I am getting myself confused with how to compose this, could somebody please offer an example? Thanks
