Unofficial API

This project is neither created nor endorsed by Yahoo Inc. Yahoo does not provide any official API to developers, nor makes any guarantees regarding service availability or API consistency. In practice however, the open source community has kept this project (and it's predecessor) working well since 2013.

Nevertheless, we make no guarantees and you use this package at your own risk. The developers (and obviously Yahoo) cannot be held responsible for any losses you may incur as a result of using this service. Use of this package is considered acknowledgement and acceptance of these terms and of it's license.

(Optional) TypeScript Love

Working with yahoo-finance2 is a joy if you're using TypeScript (but you don't have to), with type checking and auto completion:

Using in the Browser (tl;dr: possible but unsupported)

This project is primarily developed to be used server-side in node. Nevertheless, due to the large number on requests on this issue, we have taken care to ensure the package can be imported in the browser too.

HOWEVER: you'll run into other challenges there that we can't help you with, particularly CORS issues when trying to query Yahoo's servers in the browser from non-Yahoo origins. Since Yahoo is specifically blocking such requests, we will not help you bypass them. (One way around this is to run your own server to proxy your requests, but we won't help you with this).
