# Overview

> API reference for the Mint Manager and Offchain Manager (Subnames) APIs with authentication and endpoints.

## Offchain Manager API

The Offchain Manager API allows you to create, update, delete, and retrieve offchain ENS subnames and their associated records by using the Namespace.

### Authentication

Some endpoints require authentication via API key using the `x-auth-token` header. You can generate API keys through the [Namespace App](https://app.namespace.ninja/offchain?activeTab=apiKeys).

```bash theme={null}
x-auth-token: YOUR_API_KEY
```
