Overview

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.

Get an API key

Sign in to the Console 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 to make your first call.

Find your way around

• Quickstart — first JSON-RPC and Data API calls, CU billing, common errors
• Supported Chains — Chain IDs, endpoint URLs, and feature support matrix
• Robinhood Chain Guide — endpoint URLs, supported methods, and tokenized stock datasets
• Robinhood Testnet Starter — RPC setup and a starter template for testnet development
• Robinhood Testnet Faucet — test ETH funding options and network checks
• API Reference — JSON-RPC methods and Data API endpoints
• Full JSON-RPC Reference — complete specifications, parameters, and return schemas for all supported methods
• Datasets — derived datasets across supported chains
• Guides — practical guides for API integration, CU management, and multi-chain workflows

Starter templates

Jumpstart your integration with official GitHub starter repositories:

• agent-quickstart — Programmatic sign-up and initial API call for AI agents and CI.
• multichain-viem — Multi-chain viem template and client setup.
• hyperevm-backfill — Chunked HyperEVM log backfill with retries and checkpoint resume.
• robinhood-stock-tokens — Robinhood Chain tokenized stock metrics and leaderboards.
• robinhood-testnet-starter — Robinhood Chain Testnet starter: keyless reads, programmatic sign-up with WebSocket logs, then mainnet.

For AI agents

Building an agent or using an AI coding assistant? Start with the AI agent guide: a keyless MCP server, llms.txt indexes, OpenAPI 3.1 specifications, and guidance on what to ask the user for when you have no API key.
