Thank you for reaching out to us.

* Yes, it is possible. You can use the Endpoint class to access that URL. For example:

news_meta_url = '/data/news/v1/metadata/A:2'
request_definition = ld.delivery.endpoint_request.Definition(
    url = news_meta_url,
    method = ld.delivery.endpoint_request.RequestMethod.GET
)
response = request_definition.get_data()
response.data.raw

You can also refer to the example on GitHub.

2. As far as I know, the LD Library doesn't support this feature.

3. Yes. Please check this example.

Hello @LBA

Question 2: Is it possible to cache authentication token (in a file ?) in order to avoid extra authentications.

Answer: The

https://developers.lseg.com/en/api-catalog/lseg-data-platform/lseg-data-library-for-python

automatically manage authentication for you once you have opened a session. An application does not need to manage any tokens. The library does not have interface to let an application retrieve the token.

However, if you are using the pure HTTP Python (or any programming languages), there is the Data Platform Python examples that store the authentication information on a text file (see the Python authentication tutorial).
