Frequently Asked Questions

Are Alpha Vantage APIs realtime?

The latest data point of each time series output is derived from the current trading day, updated to the minute.


What is the timeframe for historical data?

Alpha Vantage provides realtime and historical equity data in 4 different temporal resolutions: (1) intraday, (2) daily, (3) weekly, and (4) monthly. Daily, weekly, and monthly time series contain 20 years of historical data. Intraday time series typically span the past 10 to 15 days.


What is the expected server-side performance (e.g., throughput time) for the API service?

While we are proud to provide free API service with no daily/weekly/monthly call limits, we recommend that API call frequency does not extend far beyond ~200 calls per minute so that we could deliver the optimal server-side performance.


I would like to improve an existing API or propose a new technical indicator / feature to Alpha Vantage. What should I do?
