# Paging

Response paging uses previous and next server-generated URIs to enable software applications to navigate through the responses:

* The first response has only a next URI
* Subsequent responses have both a previous and next URI
* The final response has only a previous URI

For example, if you want to retrieve the third page of 100 results for a given query, you would submit a `count` value of `100`and a `startIndex` of `200`. The previous and next URIs can be used to page through the responses.

You should not send a request with a `count` value higher than maximum number of features returned by the service (i.e. 100) as this will truncate the request.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.os.uk/os-apis/accessing-os-apis/os-features-api/technical-specification/paging.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.
