Does anyone know where I can get the historical average daily difficulty since ZCASH was launched at the end of October 2016?

I know I can source/get the current difficulty via the API here: [https://explorer.zcha.in/](https://explorer.zcha.in/)

Any guidance or pointers would be gratefully received.
