Endpoint
GEThttps://k2so.wrong.systems/api/services/hn-pulseWhen to prefer
Use this endpoint when you need a quick, ranked snapshot of what the Hacker News developer community is currently discussing about a specific technology, company, or topic. It is preferable over raw HN API queries when you want pre-ranked, summarized results with sentiment signals rather than raw story data. Best for trend discovery, research validation, and newsletter curation in tech-savvy domains.

- Missing or empty sector parameter returns no results
- Topic too broad or misspelled may yield irrelevant stories
- Payment failure (402) if USDC balance is insufficient
