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 its license.

See the Explanatatory Documentation and Full API Documentation.

Particularly, make sure to read the notes there on ERROR HANDLING. Be aware that if a stock gets delisted, Yahoo removes all related data, including historical (and chart) data from periods before the delisting occurred (i.e. queries that worked before will start failing, and there is no way to retrieve this data again).

(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

It's not possible to run this in the browser, due to CORS and cookie issues. You should execute calls on a server or in a serverless or edge function, and pass this data to the browser as required. See the CodeSandbox above for examples. Use React Server Components, trpc, or other strategies to maintain types.
