-                1. explicit argument
-                2. LANGGRAPH_API_KEY
-                3. LANGSMITH_API_KEY
-                4. LANGCHAIN_API_KEY
-        headers: Optional custom headers
-        timeout: Optional timeout configuration for the HTTP client.
-            Accepts an httpx.Timeout instance, a float (seconds), or a tuple of timeouts.
-            Tuple format is (connect, read, write, pool)
-            If not provided, defaults to connect=5s, read=300s, write=300s, and pool=5s.
+        url:
+            Base URL of the LangGraph API.
+            – If `None`, the client first attempts an in-process connection via ASGI transport.
+              If that fails, it falls back to `http://localhost:8123`.
+        api_key:
+            API key for authentication. If omitted, the client reads from environment
+            variables in the following order:
+              1. Function argument
+              2. `LANGGRAPH_API_KEY`
+              3. `LANGSMITH_API_KEY`
+              4. `LANGCHAIN_API_KEY`
+        headers:
+            Additional HTTP headers to include in requests. Merged with authentication headers.
+        timeout:
+            HTTP timeout configuration. May be:
+              – `httpx.Timeout` instance
+              – float (total seconds)
+              – tuple `(connect, read, write, pool)` in seconds
+            Defaults: connect=5, read=300, write=300, pool=5.
 
     Returns:
-        LangGraphClient: The top-level client for accessing AssistantsClient,
-        ThreadsClient, RunsClient, and CronClient.
+        LangGraphClient:
+            A top-level client exposing sub-clients for assistants, threads,
+            runs, and cron operations.
