Thank you for reaching out to us.

Yes, you can use the Filings API with Python. Please refer to the following articles.

• Introduction To Filings - Python
• Using AI modeling to interpret 10-Q filings

The API uses an organization PermID so you need to convert ISINs to organization PermIDs. Please refer to the articles above.

identifier = "BERM.KL"
start = "2025-06-01T00:00:00Z"
end = "2025-06-30T23:59:59Z"
response = filings.search.Definition(
    query = FilingsQuery().orgid(SymbolLookup(ric=identifier).convert())
                          .start_date(start)
                          .end_date(end)
                          .limit(100)
                          .graphQL
).get_data()
response.data.df

The output is:

However, you may need the Data Platform account to access the Filings API. Please contact your LSEG account team or Sales team directly for more information.

According to the code that uses only an application key, you are using the desktop session.

I tested the code and it doesn't work on my desktop session. It returns <NA>.

The platform session (RDP) requires an username, password, and application key. All RDP APIs are available on the API docs.

Please contact your LSEG account team or Sales team directly to verify this.

Moreover, please use the LSEG Data Library for Python instead.

The samples are available on GitHub.
