# Platforms

Where Mentio looks, how often, and how far back a new keyword reads, platform by platform.

A keyword's term is searched on thirteen platforms. A keyword can also collect [reviews](/platforms/reviews) and read [RSS feeds](/platforms/rss) of any site.

Everything lands in one feed, with the same mention shape, filters, alerts and price.

Reviews come from apps on the App Store and Google Play, companies on Trustpilot and places on Google.

**Last 30 days** is the look-back a keyword gets when it is created or turned on for a platform: the newest few matching posts of the last month.

On Instagram it reads the last 7 days. Either way, the feed is not empty on day one.

After that a keyword reads only what is published while it listens, never the time it was paused.

A mention is as fresh as the platform's own API allows; the pipeline adds under a minute. A keyword's `polling` array reports, per platform, the last poll and how many polls in a row found nothing new.

## Choosing platforms [#choosing-platforms]

A keyword searches every platform unless you say otherwise. `platforms` on `POST /v1/keywords` takes:

* A list of platforms.
* `null` for all of them, including any added later.
* `[]` to search the term nowhere, for a keyword that only [collects reviews](/platforms/reviews) or reads [feeds](/platforms/rss).

An excluded platform costs nothing: nothing from it is fetched or matched.

On a mention the platform is `post.platform`, and `platforms=reddit,x` filters the list by it.

```bash
curl -X PATCH https://api.mentio.dev/v1/keywords/kw_123 \
  -H "Authorization: Bearer $MENTIO_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "platforms": ["reddit", "hackernews", "github"] }'
```

## Price [#price]

The same on every platform: a keyword is $5 a month, a matched mention $0.008, whatever platform it came from. See [Billing](/billing).
