Vintage dates are the release dates for a time series, excluding those releases in which the data did not change. To obtain a list of vintage dates for a particular series, you can enter the following URL in your web browser and specify the series ID of the series that you are interested in. For example, the following URL retrieves a list of all vintage dates for the MICH series, showing the median expected price change (the next 12 months from the Survey of Consumers):
http://api.stlouisfed.org/fred/series/vintagedates?series_id=MICH&api_key=your_fred_apikey
The resulting list of observations is too long to show here—172 vintage dates, ranging from 1999-02-26 to 2013-05-31. You can get only the vintage dates that you want by specifying the VINTAGE= option.
