Is there an API for Poloniex Lending Fees?

I'm attempting to reconcile trading activity across accounts on several crypto trading platforms including Poloniex.

Poloniex provides the following API https://poloniex.com/support/api/

Using this api I've sourced:

• Buys & Sells - returnTradeHistory
• Transfers - returnDepositsWithdrawals
• Loan Earnings - returnLendingHistory

I've noticed the following two issues:

1. Lending Fees that are available on the Trade History page in poloniex are not returned via the returnTradeHistory endpoint.
2. Loan Earnings via returnLendingHistory isn't returning all records regardless of limit parameter.

I can survive the Loan Earnings issues by manually exporting since I rarely lend.

The missing Lending Fees however are vary annoying. If anyone knows of a hidden Endpoint, or an argument I need to pass to returnTradeHistory let me know.

Thanks

Still no official reply from Poloniex, but this is a gist of what's working for me.

Basically web scraping with Python Selenium complete with login and 2factor auth.

Would be great if Poloniex provided an official API solution.
