# Access the API

To access the API, you need to send a GET request to our official SERP API endpoint and include the `engine=yandex` parameter.

The official SERP API endpoint is:

* `https://serpapi.webscrapingapi.com/v2`

{% hint style="info" %}
You can use this as the base URL for the Yandex API: **`https://serpapi.webscrapingapi.com/v2?api_key=<YOUR_API_KEY>&engine=yandex`**
{% endhint %}

### The API Key

Authorising requests to the SERP API is made via the `api_key` parameter, that needs to be included in the base URL. Failing to pass this <mark style="color:yellow;">**required**</mark> parameter will generate a `401` HTTP code. If you haven't got your API key yet, you can do so by [registering a new account](/readme/registration.md) and by subscribing to the SERP API service inside the Dashboard.&#x20;

In the following examples, we will refer to the API key by using this syntax:**`<YOUR_API_KEY>`**

{% hint style="warning" %}
In order to prevent unauthorised access to your subscription plan, please do not include your personal API key in any public code (for example on GitHub).
{% endhint %}
