Scald Services is Services resource (hook_services_resources callback) for creating Scald atoms (media), eg. via json.
Currently only atom creation, not retrieval (easy to add, we'll see what the interest-level is like).
Works with uploaded files of any atom type (tested with atom types: image, audio, video, file). Also works with Scald Youtube and Scald Vimeo.
This project is provided as a features module. You need to have features installed.
