Project of rss feed for YYER

We want to post RSS feed updates to multiple social networks on autopilot. We have many websites and we are looking for a free solution that can post directly from our RSS feeds (of different websites) to social networks. Also we have a Paid [login to view URL] account which has an API through which it is possible if someone knows to do it via their API : [login to view URL] We also have a Zapier account as well. PS : We think it is possible through a custom php script that can GET data from RSS feeds on update and POST to the [login to view URL] API or using a Zapier Zap of RSS feed along with a python snippet webhook.
