REST API Integration

Integrate indexed blockchain data into your applications using the OpenScan.AI REST API.

The REST API is the primary integration surface: every page on xdcscan.io is backed by public endpoints you can call from any language. No proprietary SDK is required — the API is Blockscout-compatible, so standard HTTP and web3 libraries work directly.

When to use the API

• Dashboards showing balances, transfers, or network stats
• Backends that need transaction history or token holder data
• Bots and automation reacting to on-chain events
• Wallets and portfolio trackers
• Analytics pipelines exporting chain data

Quick example

curl https://xdcscan.io/api/v2/addresses/0x1234567890abcdef1234567890abcdef12345678

const res = await fetch(
  "https://xdcscan.io/api/v2/addresses/0x1234567890abcdef1234567890abcdef12345678",
);
const { coin_balance } = await res.json();
console.log(Number(coin_balance) / 1e18, "XDC");
