```

Example prompt: Give me today's ranked digest of high-signal developer news — AI, devtools, security, and infra — with scores and discussion volume pulled from Hacker News.

## When to prefer this

Choose this endpoint when you need a pre-curated, scored, and tagged daily digest of developer-relevant Hacker News content without having to scrape or parse raw HN data yourself. Ideal for building daily briefings, monitoring dev community sentiment, or tracking what's gaining traction in AI, devtools, security, and infra. Prefer this over raw HN API calls when you want ranked, filtered signal rather than raw firehose data.

## Known failure modes

- Stale data if Hacker News feed was recently unavailable
- Empty or thin results during low-activity periods (weekends, holidays)
- Payment failure if USDC balance is insufficient for the $0.02 per-call fee
- Rate limiting or temporary unavailability of the upstream data source
- No filtering options available — results always cover the full 24h window across all supported categories

## How this service works

A ranked, tagged digest of the last 24h of high-signal Hacker News stories, scored by engagement, with links and discussion volume. Every row is classified across eleven topics — ai, devtools, data, infra, security, web, hardware, plus policy, business, science, culture — and carries a developer_relevant flag, so you can keep the engineering stories and drop the front page's politics, science and obituaries, which are about half of a typical day. Built from public Hacker News data.…

## Output

A ranked list of developer news items from the last 24 hours, each with a title, link, topic tags (AI, devtools, security, infra), a relevance/signal score, and discussion volume metric, sourced from Hacker News.
