+
+For [LocalAI](https://localai.io), the OpenAI client can be used by specifing a "fake" `OPENAI_API_KEY` ( there is no need to specify a real OpenAI key ):
+
+```python
+""" 
+Basic example of scraping pipeline using SmartScraper from text
+"""
+from scrapegraphai.graphs import SmartScraperGraph
+
+# Note: You can actually leave as-is
+OPENAI_API_KEY = "YOUR_API_KEY"
+
+graph_config = {
+    "llm": {
+        "api_key": OPENAI_API_KEY,

+        "temperature": 0,
+        "base_url": "http://localhost:8080",
+    },
+}

+smart_scraper_graph = SmartScraperGraph(
