+# playgrounds_subgraph_connector
+
+Playgrounds API is a service provided by [Playgrounds Analytics](https://playgrounds.network) to streamline interfacing with decentralized subgraphs (indexed blockchain datasets).
+
+The `PlaygroundsSubgraphConnector` is a tool designed for LLM agents to seamlessly interface with and query subgraphs on The Graph's decentralized network via Playgrounds API.
+
+This tool is specifically designed to be used alongside [Llama index](https://github.com/jerryjliu/llama_index) or [langchain](https://python.langchain.com/docs/modules/agents/tools/custom_tools)
+
+- To learn more about Playgrounds API, please visit our website : https://playgrounds.network/
+- Obtain you Playgrounds API Key and get started for free here: https://app.playgrounds.network/signup
+- Find any Subgraph (dataset) you need here: https://thegraph.com/explorer
+
+## Advantages of this tool:
+
+- **Easy access to Decentralized Subgraphs (Datasets)**: No need for wallet or GRT management.
+- **LLM x Blockchain data**: Develop Ai applications that leverage blockchain data seamlessly.
+
+## Basic Usage:
+
+To utilize the tool, simply initialize it with the appropriate `identifier` (Subgraph ID or Deployment ID) and `api_key`. Optionally, specify if you're using a deployment ID.
+
+```python
+import openai
+from llama_index.agent import OpenAIAgent
+from llama_hub.tools.playgrounds_subgraph_connector.base import PlaygroundsSubgraphConnectorToolSpec
+
+def simple_test():
+    """
+    Run a simple test querying the financialsDailySnapshots from Uniswap V3 subgraph using OpenAIAgent and Playgrounds API.
+    """
+    # Set the OpenAI API key
+    openai.api_key = 'YOUR_OPENAI_API_KEY'
+    
+    # Initialize the tool specification with the subgraph's identifier and the Playgrounds API key
+    connector_spec = PlaygroundsSubgraphConnectorToolSpec(
+        identifier="YOUR_SUBGRAPH_OR_DEPLOYMENT_IDENTIFIER", 
+        api_key="YOUR_PLAYGROUNDS_API_KEY", 
+        use_deployment_id=False  # Set to True if using Deployment ID
+    )
+    
+    # Setup agent with the tool
+    agent = OpenAIAgent.from_tools(connector_spec.to_tool_list())
+    
+    # Make a query using the agent
+    response = agent.chat(
+        'query the financialsDailySnapshots for id, timestamp, totalValueLockedUSD, and dailyVolumeUSD. only give me the first 2 rows'
+    )
+    print(response)
+
+if __name__ == "__main__":
+    simple_test()
+
+```
+
+Visit here for more in-depth [Examples](https://github.com/Tachikoma000/playgrounds_subgraph_connector/blob/main/examples.ipynb).
+
+This loader is designed to be used as a way to load data into [LlamaIndex](https://github.com/jerryjliu/gpt_index/tree/main/gpt_index) 
+and/or subsequently used as a Tool in a [LangChain](https://github.com/hwchase17/langchain) Agent.
