OpenLayer - Adding XML/JSON File on a Map

I need a Guy for a small Job - i will load from a API some Datas - in all 1-3 MB every Minute. This Datas should then shown on a OpenLayer3 Map. Only the Layer should refresh any Minute (after loading the Datas) Datas comes in zip file and need to unpack and to display. Icons on Map need then to shown by click in a Popup (in a table). Link and Password of API Access doesnt have to show (hide from others) if usefull done, i will in steps extend this map.
