Via the python API, what is the most cost-efficient way of obtaining the news headline of a given news category (e.g., scheduled events) from a date closest to a given input date for a given list of different ISINs? More precisely, the inputs are * a list of ISINs, * a date, * a news category while the outputs should be (separately for each each of the input ISINs) * the datetime of the news headline on or closest to the input date * the news headline ID of said news headline

Most recent news headlines of specific news category for multiple ISINs

Via the python API, what is the most cost-efficient way of obtaining the news headline of a given news category (e.g., scheduled events) from a date closest to a given input date for a given list of different ISINs?

More precisely, the inputs are

a list of ISINs,
a date,
a news category

while the outputs should be (separately for each each of the input ISINs)

the datetime of the news headline on or closest to the input date
the news headline ID of said news headline

Thank you for reaching out to us.

You can use the LSEG Data Library for Python to retrieve news headlines. The news example is on GitHub.

Typically, it uses the same news query used in the News Monitor Workspace application. You can contact the helpdesk support team directly via LSEG Support for news queries used to retrieve required headlines.

Otherwise, you can use the news interface in the Content layer to retrieve the raw headlines data.

Thanks for your response @Jirapongse.

I previously reached out to LSEG Support, who advised me to ask the question here.

The example & links you are referring to do not contain an answer my question.

Please advise on how to use the LSEG Data Library for Python to obtain, for a given ISIN & given news category & given date, the date-stamp & news ID of the news headline that is date-wise closest to the given date (or on the given date, if such a news headline exists).

As we see in the example, the ld.news.get_headlines method requires the following parameters.

  Parameters

    ----------

    query: str

        The user search query for news headlines.

    count: int, optional

        Count to limit number of headlines.

    start: str or timedelta, optional

        Beginning of date range.

        String format is: '%Y-%m-%dT%H:%M:%S'. e.g. '2016-01-20T15:04:05'.

    end: str or timedelta, optional

        End of date range.

        String format is: '%Y-%m-%dT%H:%M:%S'. e.g. '2016-01-20T15:04:05'.

    order_by: str or SortOrder

        Sort order for headline items.

You can specify a news query, start date and end date when calling this method. For example:

ld.news.get_headlines('US4592001014', start="2025-09-25T00:00:00", end="2025-10-28T23:59:59")

The output looks like this:

'US4592001014' is a news query. It is the same news query used in the News Monitor app.

You can use the News Monitor app to generate a news query and then use the news query with the ld.news.get_headlines method to get the news headlines related to the news query.

Otherwise, please contact the helpdesk team to get a news query.
