In this quickstart you will learn how to create and manage intellectual property (IP) assets.

Contact sales to enable this API on your project.

​
What are IP credentials?

IP credentials are onchain records of intellectual property rights and authorship, enabled by Story Protocol’s infrastructure and issued using Crossmint’s APIs.

​
Integration steps

​
1. Create a Developer Account

To get started, create a developer account in the Crossmint Staging Console. Open that link, sign in, and accept the dialog to continue.

Crossmint offers two consoles: staging, for development and testing, and production.

​
2. Get an API Key

Once you log in to the console, the next step is to create an .

Click the "Integrate" tab and click on the "API Keys" option on top.

Within the “Server-side keys” section, click the “Create new key” button in the top right. Then, check the necessary scopes under the “Minting API” category: nfts.create, nfts.read, collections.create, nfts.update and create your key. Save this key for the next step.

​
3. Create an IP Collection

First, let’s create an IP collection to hold our IP assets:

createIPCollection.js
const apiKey = "YOUR_API_KEY";
const env = "staging"; // or "www"

const url = `https://${env}.crossmint.com/api/v1/ip/collections`;
const options = {
    method: "POST",
    headers: {
        accept: "application/json",
        "content-type": "application/json",
        "x-api-key": apiKey,
    },
    body: JSON.stringify({
        metadata: {
            description: "A collection of intellectual property assets",
            name: "My IP Collection",
            symbol: "MPA",
        },
        chain: "story-testnet",
    }),
};

fetch(url, options)
    .then((res) => res.json())
    .then((json) => console.log(json))
    .catch((err) => console.error("error:" + err));

Save the collection id from the response for the next step.

​
4. Create an IP Asset

Now, let’s create an IP asset within our collection:

createIPAsset.js
const apiKey = "YOUR_API_KEY";
const env = "staging"; // or "www"
const collectionId = "YOUR_COLLECTION_ID";

const url = `https://${env}.crossmint.com/api/v1/ip/collections/${collectionId}/ipassets`;
const options = {
    method: "POST",
    headers: {
        accept: "application/json",
        "content-type": "application/json",
        "x-api-key": apiKey,
    },
    body: JSON.stringify({
        owner: "email:creator@example.com:story-testnet",
        nftMetadata: {
            name: "Snowflake Funk",
            description: "A disco song for the winter holidays",
            image: "https://cdn2.suno.ai/image_large_c001fd6e-d6cd-474f-a7b6-6e6a9b3e2515.jpeg",
        },
        ipAssetMetadata: {
            title: "Snowflake Funk",
            createdAt: "2025-02-11T11:13:00",
            ipType: "music",
            creators: [
                {
                    name: "John Doe",
                    email: "john.doe@example.com",
                    crossmintUserLocator: "email:john.doe@example.com:story-testnet",
                    contributionPercent: 100,
                },
            ],
            media: [
                {
                    name: "Snowflake Funk",
                    url: "https://cdn1.suno.ai/c001fd6e-d6cd-474f-a7b6-6e6a9b3e2515.mp3",
                    mimeType: "audio/mpeg",
                },
            ],
            attributes: [
                {
                    key: "Suno Artist",
                    value: "InfluentialCoda427",
                },
                {
                    key: "Source",
                    value: "Suno.com",
                },
            ],
        },
    }),
};

fetch(url, options)
    .then((res) => res.json())
    .then((json) => console.log(json))
    .catch((err) => console.error("error:" + err));

Save the IP asset id from the response for the next steps.

​
5. Retrieve an IP Asset

To retrieve an IP asset:

getIPAsset.js
const apiKey = "YOUR_API_KEY";
const env = "staging"; // or "www"
const collectionId = "YOUR_COLLECTION_ID";
const ipAssetId = "YOUR_IP_ASSET_ID";

const url = `https://${env}.crossmint.com/api/v1/ip/collections/${collectionId}/ipassets/${ipAssetId}`;
const options = {
    method: "GET",
    headers: {
        accept: "application/json",
        "x-api-key": apiKey,
    },
};

fetch(url, options)
    .then((res) => res.json())
    .then((json) => console.log(json))
    .catch((err) => console.error("error:" + err));

​
6. Update an IP Asset

If needed, you can update an IP asset:

updateIPAsset.js
const apiKey = "YOUR_API_KEY";
const env = "staging"; // or "www"
const collectionId = "YOUR_COLLECTION_ID";
const ipAssetId = "YOUR_IP_ASSET_ID";

const url = `https://${env}.crossmint.com/api/v1/ip/collections/${collectionId}/ipassets/${ipAssetId}`;
const options = {
    method: "PATCH",
    headers: {
        accept: "application/json",
        "content-type": "application/json",
        "x-api-key": apiKey,
    },
    body: JSON.stringify({
        ipAssetMetadata: {
            title: "Snowflake Funk",
            createdAt: "2025-02-11T11:13:00",
            ipType: "music",
            creators: [
                {
                    name: "John Doe",
                    email: "john.doe@example.com",
                    crossmintUserLocator: "email:john.doe@example.com:story-testnet",
                    contributionPercent: 90,
                },
                {
                    name: "Frank L",
                    crossmintUserLocator: "email:frank.l@example.com:story-testnet",
                    contributionPercent: 10,
                },
            ],
        },
    }),
};

fetch(url, options)
    .then((res) => res.json())
    .then((json) => console.log(json))
    .catch((err) => console.error("error:" + err));
