Frequently Asked Questions

I have got my API key, now what?

Welcome to Alpha Vantage! Getting started is easy:

❚ If you would like to start coding right away, the open-source community has developed over 400 libraries and wrappers for Alpha Vantage - you may want to give them a try.

❚ If you are a spreadsheet user (e.g., Excel or Google Sheets), please check out our dedicated spreadsheet add-ons.

❚ Financial market data is a complex and evolving subject. You may refer to this article that describes what makes a stock API reliable, robust, and enterprise-ready. And you can always drop us a note at support@alphavantage.co anytime!


Are there usage/frequency limits for the API service?

We are proud to provide free stock API service for our global community of users and recommend that you make API requests sparingly (up to 5 API requests per minute and 500 requests per day) to achieve the best server-side performance. If you would like to target a larger API call volume, please visit premium membership.


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 contact us anytime and we can go from there!
