A change appears to have been put in place starting right around the beginning of August 2018 for AlphaVantage's API. Prior to August, GnuCash could retrieve all 16 stocks I'm monitoring with little to no problem (occasionally feeds weren't updated at the time I checked). As of Aug 1, 2018 the free API has a call limit of 5/minute. It doesn't return an error, but instead sends back a result of code 200, and a content of the following JSON: '{ "Information": "Thank you for using Alpha Vantage! Please visit https://www.alphavantage.co/premium/ if you would like to have a higher API call volume." }', This isn't caught by the AlphaVantage fetch function and results in any calls after the 5th to return the above result. It might be feasible to check for a return code of 200 and a content that just contains an "Information" key and if this result occurs, putting the module to sleep for 60 seconds before continuing. This way if someone has a premium API key, they'd just keep fetching the quotes and those with just the lowly free API key won't get errors in other apps, like GnuCash that prevent some automated updating.
