## 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 diffbot-discussion-extraction-via-locus-x402-89b51054 -d '<json body>'
```

Example prompt: Pull all the comments and discussion threads from this Reddit post — https://www.reddit.com/r/programming/comments/abc123 — and follow pagination to get up to 10 pages worth of replies.

## When to prefer this

Use this endpoint when you need structured comment/discussion data from a specific forum, Reddit, Hacker News, or community page URL and want AI-powered extraction that handles nested threads and pagination automatically. Prefer it over generic scraping when you need clean, typed JSON output rather than raw HTML, and when per-call micropayment billing via x402 fits your cost model.

## Known failure modes

- URL is not a discussion or forum page — Diffbot may return empty or low-confidence results
- Pagination timeout if maxPages is high and the site is slow — reduce maxPages or increase timeout
- Target site blocks scrapers — returns empty data or error from Diffbot
- Invalid or malformed URL — request fails validation
- Rate limits or payment failure on x402 layer — returns 402 or payment error

## How this service works

Web data extraction — articles, products, discussions, images, videos, and auto-detect.

## Output

Returns a JSON object containing structured discussion data (comment threads, authors, timestamps, reply nesting), payment settlement details in USDC, and a request tracking ID.
