## 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 reddit-comments-scraper-7141b1a6 -d '<json body>'
```

Example prompt: Can you scrape the comments from this Reddit thread — https://www.reddit.com/r/MachineLearning/comments/abc123/some_post/ — and get me up to 500 comments per post? Don't include NSFW content.

## When to prefer this

Choose this endpoint when you need structured, pay-per-use access to Reddit post and comment data without managing your own scraping infrastructure. It is especially useful for collecting large comment trees across multiple posts in a single call, with built-in caps to control data volume. Prefer it over general-purpose web scrapers when you want Reddit-specific parsed fields like postId, parsedId, and data type classification out of the box, and when you only want to pay for successful, non-empty results.

## Known failure modes

- Invalid or inaccessible Reddit URL returns empty items array (not charged)
- Share links using /s/ format are unsupported and will fail
- Private or deleted Reddit posts return no data
- Rate limits or Reddit blocks may cause empty runs (not charged)
- Malformed URL input causes request rejection

## How this service works

Pay-per-call structured web data. Failed or empty runs are not charged.

## Output

Returns a JSON object with a count of total items, a product identifier ('reddit-comments'), and an array of items where each item represents either a post or a comment, including fields for ID, URL, post ID, post URL, data type, parsed IDs, and post title.
