YFinance changed their api's (or their security)

[TobiasFP]

Hi.
There seams to be an issue with the finance-go, since yFinance changed its encryption keys.
Apparantly they change their encryption keys every day or even sometimes more than once a day.
This has lead to finance-go not working for a while.
yFinance has the same issue:
ranaroussi/yfinance#1407

I just wanted to bring it to your attention. I have been very happy with this library, so thank you very much for your work.

v6 of the API seems to work, not 7.

@ktpx You saved me! :)

I think they pulled the plug on v6 now. :(

All projects I see using the Yahoo API are facing this. There is this nugget I got from the ticker issue report on the subject:

https://stackoverflow.com/questions/76065035/yahoo-finance-v7-api-now-requiring-cookies-python

Not sure how/if that helps...

Saw somewhere that for instance, an url like this:
https://query2.finance.yahoo.com/v6/finance/quoteSummary/AAPL?modules=financialData
is working, but I'm not sure if the data structures are the same.
Is someone working on a patch?

Looks like we're out of luck. 😢

Totally different structure than the quotes. This show financial data. But atleast one can grab the currentprices.

Crumb is a param that is easy to gain, not sure how it will behave in long term.

For now, it is possible to generate crumb via https://query2.finance.yahoo.com/v1/test/getcrumb and then pass crumb value as param https://query2.finance.yahoo.com/v7/finance/quote?symbols=AAPL&crumb=abcdef.g. (Works with v7 only)

I have had the same crumb for a few days now, so it's possible to cache it locally on disk to avoid this call.

If you inspect the cookie header, it says one year. "Expires=Wed, 5 Jun 2024 22:54:09 GMT"

Hi there, is there any workaround I could use to test ? This is broken for a while.

So I have a fix for this and I have opened a PR for it. Not sure who should be reviewing it.
I also have "modernized" the finance-mock project used to test finance-go. PR can be found here: piquette/finance-mock#1
