Is it possible that ticker.info is reporting fewer keys than before? (since circa Aug 1 2023)

[init-js]

Simple code that reproduces your problem

I was banking on Ticker.info giving me the company address, the name of the CEO, etc. It used to, but no longer seems to be doing that since... maybe two days ago (Aug 1st?)

Maybe this is a recurring event -- yahoo data model changing under our feet?

I'm new to yfinance. I read elsewhere that it can return bad data when makeing too many requests. I doubt I'm being throttled, but it's not impossible. (I've made 100 request tops in one week).

>>> import yfinance as yf
>>> yf.__version__
'0.2.26'
>>> t = yf.Ticker("MSFT")
>>> t.info

I unfortunately don't have a snapshot of what the old info used to look like, but from memory, it seems to match what this tutorial is giving as example output: https://analyzingalpha.com/yfinance-python

dhr = yf.Ticker('DHR')
info = dhr.info
info.keys()
dict_keys(['zip', 'sector', 'fullTimeEmployees', 'longBusinessSummary',
 'city', 'phone', 'state', 'country', 'companyOfficers', 'website',

'grossProfits', 'freeCashflow', 'targetMedianPrice', 'currentPrice',
'earningsGrowth', 'currentRatio', 'returnOnAssets', 'numberOfAnalystOpinions',

Notice that keys fullTimeEmployees, city, phone, fax etc All of those are gone in the current info.

Bad data proof

I'm not saying that it's returning bad data, but it definitely has a different shape than I expected.

Based on my previous experience a few days ago, and this online tutorial:

https://analyzingalpha.com/yfinance-python

(search for "dhr.info")

yfinance version

0.2.26

Python version

3.10+

Operating system

WSL2

[ValueRaider]

Others have seen change #1645. Info was returning ~150 entries

[init-js]

Looks like it's back to normal today...

Spooky. Leave issue open in case happens again.

[jkoestner]

I had an issue yesterday as well, but since all yfinance is doing is giving us a nice format I'm also keeping tabs on the query to yahoo shown below. #1592 also discusses how to get the crumb.

Same issue here, any solution available?

[vismoh2010]

For the past 1 week, my app has not been working because of this, please rectify this soon, or at least give some update.

[ValueRaider]

Does #1657 help?

[vismoh2010]

#1657 fixes all my issues @ValueRaider. Please merge ASAP.

Hello,
Same problem.
After migrating to v10 api version, I notice that some key is missing like sector, company information, etc...

[ValueRaider]

I think I stumbled upon root problem and fixed it in #1657 (commit 2f241e6). Fix doesn't have to be in same PR, but (i) info broken anyway and (ii) I need more competent people to test #1657 and feedback/improve so using fix as bait.

[nikso91640]

Hi guys,

I'm still having this problem, because there's a lot of information missing.

I've tried to figure out how to proceed, but I need your help.

Thank you and have a great holiday season!

[ValueRaider]

Because code has changed significantly, and not clear what versions y'all were running, I'm closing this. Create new bug report if issue still happens with details.
