QUICKS – “QKDN Universal Interface for Communication between KMS and SDN” – is an OpenAPI specification publised by the AURORA KMS and SDN team. It defines all relevant endpoints and sequences for and SDN controlled KMS.
It is available open source with an MIT license on github.

The API is implemented as a https REST API in a bidirectional setup, where the KMS and SDN Agent host a server and can act as a client with the other peer. Therefore, two APIs are described. The API further considers both the ETSI 014 and ETSI 004 application interface setups.
Alongside the OpenAPI specification, sequence diagrams are also given.
Since OpenAPI specification files are not directly easily readable, a PDF version and webpage version are also provided on the github page.
