## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability api-direct-reddit-subreddit-posts-29fefbdc
```

Example prompt: Can you pull the top 50 hot posts from r/MachineLearning on Reddit and include AI sentiment analysis for each one so I can see the emotional tone of the community right now?

## When to prefer this

Choose this endpoint when you need structured Reddit post data from a specific subreddit — especially when you need bulk posts (up to 1000 via 40 pages), flair-based filtering, or AI emotion analysis layered on top. Prefer this over general web search endpoints when the target is specifically a Reddit community rather than a keyword search across all of Reddit.

## Known failure modes

- Subreddit not found or misspelled — 404 or empty results
- Both subreddit and url provided simultaneously — validation error
- posted_ago parameter used with a sort other than top or controversial — rejected
- Subreddit is private or banned — access denied
- Pages exceeding 40 — validation error
- Rate limiting or Reddit API unavailability — upstream timeout or 5xx

## How this service works

Get a subreddit's posts by name or URL.

## Output

Returns an array of Reddit posts from the specified subreddit, each containing post title, content, metadata (score, comments, flair, timestamp, author), and optionally a sentiment object with emotion scores (joy, trust, fear, surprise, sadness, disgust, anger, anticipation each 0-100), dominant emotion, emotional intensity (0-10), and polarity label.
