Soon (this week) to be released is a brand new generation of AmiQuote - version 4.0 that is the very first version to bring to you user-definable data sources. From now on convenience and automation of AmiQuote will not be limited to pre-defined sources. You will be able to define your own and quickly adopt new web-based sources into the list.
A new version will come with examples of user-definable sources that include Alpha Vantage intraday and EOD, Tiingo Intraday IEX and more.
