## 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 companyfacts-dev-hacker-news-search-api-c95cd61a
```

Example prompt: Search Hacker News for stories about 'large language models' posted after January 1, 2024 and give me the titles, authors, point counts, and URLs.

## When to prefer this

Choose this endpoint when you need structured, machine-readable metadata about Hacker News stories — including point counts, comment counts, authors, and timestamps — especially when filtering by keyword or date. Prefer it over scraping HN directly or using the Firebase HN API when you need full-text search capability with parsed fields and are comfortable with per-call micropayment via x402.

## Known failure modes

- Ambiguous or missing query returns zero results
- date_from value in wrong format returns an error
- story_ids referencing deleted or non-existent stories returns empty items
- Rate limiting or payment failure returns 402 or access denied
- Very broad queries may return truncated or paginated results without clear indication

## How this service works

Open job postings read first-hand from the applicant-tracking system behind a company's careers page: Greenhouse, Ashby, Lever or Workable. Includes a directory of 8532 company job boards, because none of the vendors publishes one. Salaries are parsed into numbers where the employer publishes them and refused where ambiguous. No personal data.

## Output

Returns a JSON object with a mode field (e.g. 'search'), a count of results, and an array of story items each containing: numeric ID, URL, type, title, author handle, domain, point score, source (e.g. 'algolia'), creation timestamp (ISO 8601), a verify URL linking back to news.ycombinator.com, and number of comments. Also includes a notes array for any metadata about the response.
