Code to test the sdk:

• for a node-js app:

import onec from "ceno-sdk";

const data = {
    "token_id": "13",
    "metadata": {
        "Title": "Reference NFT",
        "Creator": "Onecdot"
    },
    "public_address": "0xB1932F9dE39c0633b77F64752f83692aD978cDD9"
}

async function mint(data) {
    const naas = new onec.naas(api_key)
    
    // var res = await naas.mintRefNFT(data)
    // console.log(res)

    var res = await naas.checkMintStatus(1267)
    console.log(res)

    var res = await naas.fetchTokenID(1267)
    console.log(res)

    var res = await naas.fetchRefTokenID(1270)
    console.log(res)

    var res = await naas.getTokenMetadataHash(13)
    console.log(res)

    var res = await naas.getRefNFTs(13)
    console.log(res)

    var res = await naas.getIpfsFiles()
    console.log(res)
    
    // var res = await naas.uploadIpfsMetaData(data)
    // console.log(res)

    // var res = await naas.getIpfsMetaData()
    // console.log(res)
}

mint(data)

• for a nextjs app (a file on the server/api side):

const onec = require('ceno-sdk')
const api_key = process.env.NAAS_APIKEY

function handler(req, res) {
	return new Promise(async (resolve, reject) => {
		if (req.method === 'GET') {
			try {
                var data = {
                    "meta_data": {
                        "Concert": "Test Service",
                        "Date": "dd-mm"
                    },
                    "info": "Optional:Some info"
                }

                const naas = new onec.naas(api_key)
                // const mintRes = await naas.mintRefNFT(data)
                // console.log(mintRes)

                var resp = await naas.checkMintStatus(1273)
                console.log(resp)

                var resp = await naas.fetchTokenID(1273)
                console.log(resp)

                var resp = await naas.fetchRefTokenID(1275)
                console.log(resp)

                var resp = await naas.getTokenMetadataHash(20)
                console.log(resp)

                var resp = await naas.getRefNFTs(20)
                console.log(resp)

                var resp = await naas.getIpfsFiles()
                console.log(resp)

                var resp = await naas.uploadIpfsMetaData(data)
                console.log(resp)

                var resp = await naas.getIpfsMetaData()
                console.log(resp)
                
				res.status(200).json({ resp });
				res.end();
			} catch (error) {
				console.log(error);
				res.status(400).send(error);
				res.end();
			}
		}
	});
}

export default handler;
