# Interact with existing Sub-Graphs One of the first features available to Closed Beta users is the ability to explore and query **predefined sub-graphs** created by the GraphAI team. These sub-graphs act as curated datasets, each focused on a specific onchain activity such as token transfers, liquidity pool movements, or wallet behavior. By starting with existing sub-graphs, users can immediately experience how GraphEngine transforms raw blockchain data into structured, queryable knowledge. You will be able to use **natural language prompts** or GraphQL queries to pull insights, test different types of questions, and see how responses are structured. This approach ensures that even without creating a custom subgraph, you can begin experimenting right away. It also provides a foundation for understanding how sub-graphs are built and what kind of insights they unlock—knowledge that will be invaluable once you move on to creating your own. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://graphai-1.gitbook.io/graphai/graphai-platform/graphengine-closed-beta/interact-with-existing-sub-graphs.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
