# Index with Graph Node

[The Graph's Nodes](https://github.com/graphprotocol/graph-node/blob/master/README.md) are an essential component for developers working with Ethereum Virtual Machine (EVM) based blockchains. They enable efficient querying and indexing of blockchain data, allowing developers to build and deploy subgraphs that define how to map and retrieve data from a blockchain. By using Graph Node's, developers can create powerful and scalable decentralized applications (dApps) that can quickly access and process blockchain data.

VeChain does not have direct RPC compatibility, but the SDK and other tools can provide a translator to make it easy to connect and access data instantly.

This section describes the steps required to set up a Graph Node that indexes different silos of information.

# 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://docs.vechain.org/developer-resources/index-with-graph-node.md?ask=<question>
```

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.
