I know that Arrcus, Cisco, Nokia, and Juniper support NETCONF/RESTCONF. I am happy to point you to a VM/Docker instance of ArcOS that will allow you to play with its RESTCONF or NETCONF interface with an OpenAPI documentation set. I am not trying to sell my product, just demonstrating that there are plenty of platforms/NOS that support this interface.

Like most programming projects, the initial learning curve is always high. I would suggest that you spend some time going through this presentation by Roman Dodin on how he went about trying to automate his network, in addition to what Kristian mentions below.
