# 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 %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.webscrapingapi.com/yandex-search-api/getting-started/access-the-api.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
