## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Reddit Subreddit Tracker

**Reddit Subreddit Tracker** collects **posts from any subreddit or global Reddit keyword search** — returning score, upvote ratio, comment count, author, flair, post type, and optionally full body text. Filter by sort order (hot/new/top/rising), time period, and minimum score. No API key or Reddit account required. $0.001/post.

Reddit is one of the richest sources of genuine community discussion — niche subreddits contain highly informed conversations that mainstream media misses. This actor makes those communities systematically queryable for research, monitoring, and content pipelines.

***

### Why use Reddit Subreddit Tracker?

1. **Trending post monitoring** — Pull `sort: "hot"` from niche subreddits daily to catch what the community is engaged with before it breaks into mainstream coverage. Hot posts on r/wallstreetbets or r/CryptoCurrency often precede price action.
2. **Brand and keyword surveillance** — Search for your company name, product, or competitor across all of Reddit. `minScore: 10` filters noise; high-score posts with your brand need attention.
3. **Newsletter and content curation** — Pull `sort: "top"` + `timeFilter: "week"` from targeted subreddits to auto-curate the best content for your audience.
4. **Community research** — Compare post volume and score distributions across related subreddits (e.g. r/learnpython vs r/Python vs r/programming) to understand community health and engagement patterns.
5. **Data pipeline input** — Feed Reddit posts into downstream analysis — sentiment scoring, entity extraction, topic modeling — as a structured starting point.

***

### How to use

1. Open the actor on Apify Store and click **Try for free**.
2. Set `subreddits` to the communities you want to monitor (e.g. `["wallstreetbets", "CryptoCurrency"]`) or set `keyword` for a global search.
3. Set `sort` and `timeFilter` (e.g. `sort: "top"`, `timeFilter: "week"` for weekly best posts).
4. Set `minScore` to filter out low-quality posts.
5. Click **Start**. Returns structured post records from Reddit.

### Input

| `keyword` | string | `""` | Search term for global Reddit search |
| `sort` | string | `"hot"` | Sort order: `hot`, `new`, `top`, `rising` |
| `timeFilter` | string | `"week"` | Time window for `top` sort: `hour`, `day`, `week`, `month`, `year`, `all` |
| `minScore` | integer | `0` | Skip posts below this score |
| `maxResults` | integer | `100` | Maximum posts to return (1–500) |

### FAQ

**What's the difference between `subreddits` and `keyword`?**
`subreddits` fetches posts directly from specific communities (r/python, r/wallstreetbets). `keyword` runs a global Reddit search and returns posts from any subreddit that match the search term. You can use both in the same run — results are deduplicated.

**How does `rising` sort work?**
Reddit's rising sort shows posts gaining velocity right now. It returns a small number of posts (typically 25–50) due to Reddit API limitations. Use it for real-time trend detection rather than bulk collection.

**Does it include stickied moderator posts?**
Yes — stickied/pinned posts may appear at the top regardless of score. Filter these out in your code by checking if `flair: "Mod Post"` or similar.

**Can I get deleted posts or comments?**
No — deleted posts/comments show as `[deleted]` or `[removed]`. The actor returns whatever Reddit's public API serves.

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
