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.
