# Hacker News Scraper

Search Hacker News using the free [Algolia HN Search API](https://hn.algolia.com/api). No Apify token or API key needed.

## Quick Start

Only dependency: `pip install requests`.

```bash
# Stories about AI content marketing in last week
python3 skills/hacker-news-scraper/scripts/search_hn.py \
  --query "AI content marketing" --days 7

# Show HN posts in last month (summary view)
python3 skills/hacker-news-scraper/scripts/search_hn.py \
  --query "" --tags show_hn --days 30 --output summary

# Comments mentioning a specific tool
python3 skills/hacker-news-scraper/scripts/search_hn.py \
  --query "LangChain" --tags comment --days 14 --max-results 20
```

## How the Script Works

1. Queries the Algolia HN Search API (`search_by_date` endpoint)
2. Uses `numericFilters=created_at_i>{unix_timestamp}` for server-side date filtering
3. Paginates until max-results reached
4. Normalizes results to a consistent schema
5. Applies optional keyword filtering (client-side)
6. Sorts by points (descending) and outputs JSON or summary

## CLI Reference

| Flag | Default | Description |
|------|---------|-------------|
| `--query` | *required* | Search query |
| `--days` | 7 | How many days back to search |
| `--tags` | story | Item type: `story`, `comment`, `ask_hn`, `show_hn` |
| `--max-results` | 50 | Max results to return |
