Try it

import { crapi, Chainrails } from "@chainrails/sdk"

Chainrails.config({
  api_key: "your_api_key_here"
})

// Get all chains
const allChains = await crapi.chains.getSupported()
console.log("All chains:", allChains)

// Get only mainnet chains
const mainnetChains = await crapi.chains.getSupported({ network: "mainnet" })
console.log("Mainnet chains:", mainnetChains)

// Get only testnet chains
const testnetChains = await crapi.chains.getSupported({ network: "testnet" })
console.log("Testnet chains:", testnetChains)
