Endpoint
GEThttps://api.x-402.online/v1/social/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to search across both Hacker News and Lemmy simultaneously without managing separate API keys or authentication. It is ideal when you want a merged, ranked view of developer and tech community discussions in one call, especially for relevance-sorted or time-windowed research. Prefer this over scraping each platform separately when you need structured metadata (score, comments, permalink, excerpt) ready for downstream analysis.
Side effects
- Missing or empty query returns no results or an error
- Unsupported sort or time-window values may yield unexpected results
- Payment not made or payment challenge fails, blocking access
- Upstream Hacker News or Lemmy API downtime causes partial or empty results
- Very niche queries return zero matching posts
