Example

const { AvnApi, SetupMode, SigningMode } = require("avn-api");
const AVN_GATEWAY_URL = "https://gateway.testnet.aventus.network";

const singleUserOptions = {
	suri: "0x5392ca60a61aea99fce14358798de93c1bc11c3696a905718738c71fae539c24", // this is from the generated example account
	setupMode: SetupMode.SingleUser,
	signingMode: SigningMode.SuriBased,
};

const avnSdk = new AvnApi(AVN_GATEWAY_URL, singleUserOptions);

// Replace with the nftID of the NFT you're trying to list.
const NFT_ID = "0xcd5...2f6";

async function main() {
	await avnSdk.init();
	const api = await avnSdk.apis();

	let request_id = await api.send.listEthereumNftForSale(NFT_ID);
