Get the Nonce of an NFT

Returns the nonce of a given NFT.

await api.query.getNftNonce(NFT_ID);

tip

If you're checking the ID for a newly minted NFT, allow time for consensus to be reached on the minted NFT.

You can get the VL_GATEWAY_URL here.

Example

const { AvnApi, SetupMode, SigningMode } = require("avn-api");
const VL_GATEWAY_URL = "https://gateway.testnet.voucherledger.com";

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

const avnSdk = new AvnApi(VL_GATEWAY_URL, singleUserOptions);

//replace with the external ref set when minting the NFT.
const EXTERNAL_REF = "https://5DA/gxV";

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

    let request_id = await api.send.getNftNonce(<NFT_ID>);
    console.log(request_id);
}

(async () => {
    await main();
})();

Example Result

REQUEST PARAMS

• nftId [required] - a string representing the NFT ID (32 bytes) to check for nonce.

JSON-RPC Example

curl https://VL_GATEWAY_URL/query \
    -X POST \
    -H "Content-Type: application/json" \
    -H "Authorization: bearer <awtToken>" \
    -d '{"jsonrpc":"2.0", "method":"getNftNonce", "params":{"nftId":"0x4184aa1d0e5a1a44d36d92b02ad07ab4285a43086f538a7e5b7d5cbd858e0e71"}, "id":1}'

result - string integer value of the current nonce for the NFT

JSON-RPC Output
