## 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 orthogonal-reddit-subreddit-posts-b46668ab
```

Example prompt: Pull the top posts from r/MachineLearning this week — sort by top with a weekly timeframe — and give me a trimmed summary of what's trending.

## When to prefer this

Use this endpoint when you need to browse or monitor Reddit subreddit posts at scale with cost-efficient pagination — particularly valuable when you need multiple pages of results, since only the first page is billed. Prefer this over general web scraping when you want structured Reddit post data with sorting and timeframe controls.

## Known failure modes

- Invalid or private subreddit name returns empty results or error
- Case-sensitive subreddit mismatch causes no results
- Changing filter parameters while passing parentRequestId starts a new billable request
- Expired or invalid pagination cursor breaks continuation
- Rate limiting or Reddit access restrictions may return errors

## How this service works

Subreddit Posts Pagination billing: call the first page normally and save billing.requestId from the Orthogonal /v1/run response. For later page, offset, or cursor calls on the same logical search, pass parentRequestId with unchanged non-pagination parameters. Valid continuation calls still get their own request IDs and quoted price, but are charged 0. Changing filters starts a new billable request.

## Output

Returns a list of posts from the specified subreddit including post titles, content, metadata (author, score, comments, timestamps), and a pagination cursor for subsequent pages. Also includes a billing requestId to use as parentRequestId for free continuation pages.
