Introduction

The Collective Defense Cloud has provided a RESTful API to query the status and the results of binaries submitted for Cb Inspection.

Example client scripts are included for reference purposes and are implemented in Python.

The Collective Defense Cloud REST API uses a set of HTTP header fields for authentication of all requests. Please refer to the REST API authentication reference for more details on these authentication parameters and how to get access to the API.
