# List the operating systems visitors used

`GET /v1/results/analytics/operating-systems`

Lists the operating systems visitors used, with each one's visitors and page views, most visitors first. It answers with a plain list, not a [table](https://developers.silktide.com/v1/concepts/tables.md).

The list stops at the ten with the most visitors. The old documentation said it takes `limit`; it ignores it, and systems past the tenth are left out rather than gathered into `Other`. `Other` is a system Silktide did not recognize.

`iconUrl` is an image on the API host for showing beside the name; `Mac` and `iOS` share one. It is `null` for systems Silktide has no icon for.

## Request

### Query parameters

- `view` (string, optional, matches `^(all|[1-9]\d*)$`): The analytics view to read: its id, the number after `/analytics/` in its address in Silktide, or `all` for all of the account's analytics. Send this or `websiteId`.
- `websiteId` (integer, optional, at least 1): Instead of `view`, a website whose analytics to read. The website must have Analytics set up.
- `sectionId` (integer, optional): With `websiteId`, a section of the website. Defaults to `0`, the whole website.
- `period` (string, optional): The date range. Defaults to `all`. The spaced forms (`-7 days`, `month to date`) are older names that keep working. `custom` needs `from` and `to`.

- `from` (string, optional): With `period=custom`, the first day, such as `2026-10-01`.
- `to` (string, optional): With `period=custom`, the last day.
- `timezone` (string, optional): The IANA time zone days are read in, such as `America/New_York`. Defaults to `UTC`.
- `filters` (map of strings, optional): Only visits matching every filter, keyed by what is filtered: `filters[url]=contains:/blog`. Each value is `{operator}:{value}`, with operator `is`, `not`, `contains`, `starts`, `gt` or `lt`. Keys include `url`, `hostName`, `entryUrl`, `exitUrl`, `event`, `outgoingUrl`, `referrer`, `source`, `medium`, `campaign`, `content`, `term`, `countryCode`, `regionCode`, `language`, `deviceType` (`desktop`, `tablet` or `mobile`), `operatingSystem` and `browser`.
