# Basics: Public

> Get started with the public access features of W3API.

What's available for the [Public service plan](/get-started/w-3-api-basics/service-plans) user:

* Node API at the corresponding [rate limits](/get-started/w-3-api-basics/service-plans#rate-limits).
* Connection code snippets.
* Public usage data.

## Use public endpoints

To enable your project to interact with a blockchain, add the blockchain's endpoint into the project's library or config file:

1. In **Navigation**, click **Chains List** to open the pane.
2. In **Chains List**, locate and click a chain you'd like to query.
   ![Select chain](/_fern-img/8aecc61391a6317209a378ec411768ccc5d9ef254f2ba96f3019b5480408ebca.webp)
3. In the **Chain** opened, select a network (**Mainnet**/**Testnet**) required for your project.

4. In the **HTTPS Endpoint** field, copy the URL and paste it into your project's library or config file.
   ![Copy URL](/_fern-img/1ce16f89ad14e8f4753cfa50633f94d8d8b1d69f8b3873af4dc3623733e56f72.webp)

Congrats — you've just added a public endpoint into your project to enable blockchain interaction.
