# Time Range

Every request covers a crawl-time window. By default it is the last 3 months, and history reaches back up to 2 years.

## The `ts` parameter

`ts` is a Unix timestamp in **milliseconds** marking the start of your search window. The window applies to when a post was **crawled**:

```bash
https://api.webz.io/cyberFilter?token=YOUR_TOKEN&q=bitcoin&ts=1743854400000
```

- Without `ts`, the window starts **3 months ago**.
- A `ts` older than **2 years** is raised to 2 years ago - that is how far history reaches.
- With `order=desc` and the default `crawled` sort, `ts` marks the end of the window instead: you get posts crawled before it, newest first. Without `ts`, that window ends now.

> [!NOTE]
> The [Segmentation API](cyber-api-segmentation) window is different: it defaults to the last month and reaches back at most 1 year.
