I had a look at the API calls which are made during opening of the scheduled exports of performance views for the logged in user. I could see that there is an API call for an endpoint which is not documented at developer page:
If it's undocumented it's not part of the public API. Not all APIs the platform itself makes use of are available to end users. It may on the roadmap to release it after it's been thoroughly vetted or it may be something they're unaware people would actually want to be able to do programmatically. You can submit it to their Ideas board to try to get some buzz around it or an idea of when it will be released.
This has been asked before in regards to the PATCH verb of that endpoint but went unanswered.
