# Quick Start

> Get authenticated and make your first API call.

This guide gets you set up with the nocnoc API — from understanding the environment to making your first authenticated request.

## Environment

nocnoc runs a single live environment. Every request you make is processed as a real transaction against real data.

| Property | Value                                 |
| -------- | ------------------------------------- |
| Base URL | `https://live.nocnocstore.com/api/v2` |
| Status   | Active                                |

<Warning>
  All requests are live. Any products you create or orders you place affect real customers. Coordinate with your Account Manager before running volume tests.
</Warning>

## Authentication

nocnoc uses API keys. Include your `SELLER_KEY` in the `X-Api-Key` header on every request. Your key is provided by the nocnoc team — contact your Account Manager if you don't have one yet.

Every request must also include the `Content-Type: application/json` header. Requests without it will return a `415 Unsupported Media Type` error.

| Header         | Value               |
| -------------- | ------------------- |
| `X-Api-Key`    | Your seller API key |
| `Content-Type` | `application/json`  |

<Note>
  No IP allowlist configuration is required. The API accepts requests from any origin IP address.
</Note>

## Your first request

```bash theme={null}
curl https://live.nocnocstore.com/api/v2/products \
  -H "X-Api-Key: YOUR_SELLER_KEY" \
  -H "Content-Type: application/json"
```

A `200` response confirms your key is valid. A `401` indicates the key is missing or incorrect.
