Clarification about LANGSMITH_ENDPOINT for accounts in the EU region

[joselpart]

Issue with current documentation:

I noticed that in the docs of the environment variables it states that LANGSMITH_API_KEY and LANGSMITH_ENDPOINT need to be set only for deployments with self-hosted LangSmith. This seems like a mistake, unless I'm misunderstanding the description.

EDIT: I realized that when I searched the website, the docs that I got back about the environment variables corresponded to the LangGraph platform, so it's not relevant to my query.

For accounts set up in the EU region, I was getting an authentication error when setting up LangSmith tracing, and stumbled upon a solution here. After an AI search, I found a note in the old docs about setting the correct endpoint in one of the how-to guides, and in the new docs, in the instructions about how to export trace data. I think it would be useful to have this information more accessible.

EDIT: I just found another mention of the endpoint for the EU region here, while going through the docs in more detail. I still think that having access from your dashboard would be useful, since it would make it more accessible.

Idea or request for content:

• Make the LangSmith endpoints more prominent in the documentation. In fact, it would be useful to be able to easily check them in the LangSmith dashboard.
