You support both raw and adjusted intraday/daily/weekly/monthly time series. What adjustment method are you using?

We use the adjustment methodology from the Center for Research in Security Prices (CRSP), an industry standard.


I have built a library/wrapper for Alpha Vantage with a specific programming language. May I open-source it on GitHub?

Certainly - we truly appreciate the help and support from the community to make Alpha Vantage even more accessible and developer-friendly. However, we ask that your language-specific library/wrapper preserves the content of our JSON/CSV responses in both success and error cases. We consider it a top priority that our users get the original debugging and troubleshooting information from Alpha Vantage.


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

We are obsessed with delivering the best user experience with the highest technical expertise. Please share your feature requests with us at [email protected].
