SkyDrive alternative with API access?

Is there any 3th party service (no MS) similar to skydrive (CRUD files in the cloud) f开发者_如何学Cree to use and with an official API (REST could be perfect but even SOAP can be ok)?

I don't need 100Gb, just few megs are ok, but accessible via API (I'm planning to develop a smartphone application).
