# Overview

> Original page: https://docs.blockvectra.com/en/

BlockVectra is a multi-chain blockchain data provider: one API key for JSON-RPC on every chain we support, and the Data API where it is available. You don't need to run your own node.

## What you get

* **JSON-RPC**: standard EVM methods (available methods vary by chain, with `debug_trace` methods on supported chains), metered by Compute Units (CU) per call.
* **Data API**: read-only REST endpoints over indexed chain data — blocks, transactions, token transfers and balances, NFTs, DEX activity, tokenized stocks, and more. Coverage and capabilities vary by chain; see [Supported Chains](https://docs.blockvectra.com/en/chains/).

## Get an API key

Sign in to the [Console](https://console.blockvectra.com/login/?next=%2Fkeys%2F) using an Ethereum wallet or GitHub / Google to automatically provision an account and create an API key.

Once you have a key, head to the [Quickstart](https://docs.blockvectra.com/en/quickstart/) to make your first call.

## For AI agents

Building an agent or using an AI coding assistant? Start with the [AI agent guide](https://docs.blockvectra.com/en/guides/ai-agents/): a keyless [MCP server](https://docs.blockvectra.com/mcp), `llms.txt` indexes, OpenAPI 3.1 specifications, and guidance on what to ask the user for when you have no API key.
