# Create Datatoken with fixed pricing

This tutorial will guide you for creating your own data NFT and a datatoken using Ocean libraries. To know more about data NFT and datatoken please refer [this page](../../core-concepts/datanft-and-datatoken.md). Ocean Protocol supports different pricing schemes which can be set while publishing an asset. Please refer [this page](../../core-concepts/asset-pricing.md) for more details on pricing schemes.

#### Configuration

See [this](configuration.md) guide on defining a `.env` file and a configuration file.

#### Create a script to deploy dataNFT and datatoken with fixed pricing.

Create a new file in the same working directory where configuration file (`config.py`/`config.js`) and `.env` files are present, and copy the code as listed below. &#x20;
