npm Package

Install via npm for JavaScript/TypeScript projects.

​
Quick Install

npm
npm install @range-security/faraday-sdk
yarn
yarn add @range-security/faraday-sdk

​
Basic Usage

import { FaradayClient } from "@range-security/faraday-sdk";

const client = new FaradayClient({
  apiKey: process.env.RANGE_API_KEY,
});

// Get a quote for cross-chain transfer
const quote = await client.getQuote({
  fromChain: "ethereum",
  toChain: "solana",
  fromToken: "USDC",
  toToken: "USDC",
  amount: "1000",
});

console.log(quote);
See the Faraday Integration Guide for complete documentation.

Community Libraries

Unofficial libraries and tools built by the Range community:
Community libraries are not officially maintained by Range. Use at your own discretion and verify security before production use.
A Python wrapper for Range APIs built by the community. bash pip install range-sdk Note: This is a community-maintained project. For official support, use direct API calls.
A Go client for Range Data and Risk APIs. bash go get github.com/community/range-go Note: This is a community-maintained project.
Building a library? Let us know and we’ll feature it here!

Code Examples

​
Data API

Fetch address information across multiple chains: 
const response = await fetch(
  'https://api.range.org/v1/address?address=CCTPiPYPc6AsJuwueEnWgSgucamXDZwBd53dQ11YiKX3&network=solana',
  {
    headers: {
      'Authorization': `Bearer ${process.env.RANGE_API_KEY}`
    }
  }
);

const data = await response.json();
console.log(data);

​
Risk API

Screen an address for sanctions: 
const address = '0x123...';

const response = await fetch(
`https://api.range.org/v1/risk/sanctions?address=${address}`,
{
headers: {
'Authorization': `Bearer ${process.env.RANGE_API_KEY}`
}
}
);

const riskData = await response.json();

if (riskData.is_sanctioned) {
console.log('⚠️ Address is sanctioned!');
// Block transaction
}
