Verified usage

Verified import paths — ran on the pinned version, not inferred.

extend_path

✓ from lseg import extend_path

✗ from lseg.data import LsegData

Initialize LSEG Data client with app key and fetch historical prices.

import os from lseg.data import LsegData from lseg.data.auth import Credentials creds = Credentials(app_key=os.environ.get('LSEG_APP_KEY', '')) client = LsegData(credentials=creds) df = client.get_history( instruments=['IBM.N'], fields=['TR.PriceClose'], start_date='2025-01-01', end_date='2025-01-31' ) print(df.head())

Debug

Known issues

breakingIn v2.0.0, the credential class moved from `lseg.data.credentials` to `lseg.data.auth`. Old imports will break.

fix

Use `from lseg.data.auth import Credentials` instead of `from lseg.data.credentials import Credentials`.

affects: >=2.0.0

breakingThe `get_history()` method no longer accepts `instrument` (singular) parameter; use `instruments` (list) only.

fix

Pass a list to 'instruments' even for a single instrument, e.g., `instruments=['AAPL.O']`.

affects: >=2.0.0

gotchaThe library requires Python >=3.9. Using older Python versions will raise ImportError.

fix

Upgrade Python to 3.9 or later.

affects: >=2.0.0

gotchaAPI keys must be granted appropriate entitlements; otherwise requests return authorization errors.

fix

Verify your LSEG app key has access to the requested data products.

affects: all
