# Filters

> [!WARNING]
> The Web Content API is **deprecated**. Use the [News, Blogs & Forums APIs](news-blogs-forums-overview) instead - same content, one endpoint per content type, and where new features land.

Besides the `q` query, you can narrow results with filter parameters passed directly in the URL. They behave like query filters but keep `q` clean.

## Using filters

```bash
https://api.webz.io/filterWebContent?token=YOUR_TOKEN&q=bitcoin&language=english&site_type=news&country=US
```

## Excluding values

Prefix any filter with `exclude_` to remove matching posts:

```bash
&exclude_site_type=discussions&exclude_country=RU
```

## Source filters

These filters describe the source site or thread:

`url`, `site`, `site_full`, `site_section`, `section_title`, `site_type`, `country`, `replies_count`, `participants_count`, `performance_score`, `domain_rank`, `rating`.

They map to the `thread.*` fields in the response.

## Topics

Use the topic filter inside `q`, for example:

```
q=topic:"climate change"
```

`topic:` supports 629 topics derived from IPTC levels 2 and 3 and grouped under the 17 categories. Values are case-insensitive; quote values containing spaces. Examples include `election`, `economy`, `climate change`, `cyber crime`, `cancer`, `tennis`, `terrorism`, and `cinema`.

Topic classification supports English, Spanish, French, Italian, Catalan, Portuguese, Chinese, Traditional Chinese, Arabic, German, Russian, and Hindi. Trust-based filtering may also classify content in additional languages.

## Syndicated content

By default, syndicated (republished) duplicates are excluded. To include them:

```bash
&includeSyndicated=true
```

> [!TIP]
> The same conditions can be written inside `q`. Filters are just a convenient, separate way to express them.
