Endpoint
POSThttps://market.datapackvibe.com/x402/demand-next-community-search-and-retrieval-product?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to quickly surface what the Hacker News developer community is currently discussing about search, retrieval, or RAG systems — especially useful for competitive research, trend spotting, or gauging practitioner sentiment without manually browsing HN. It is pre-scoped to the search/retrieval/RAG domain, making it more targeted than a general HN search API.
Side effects
- No results found for highly specific or uncommon query terms
- Payment failure if USDC balance is insufficient (x402 protocol)
- Rate limiting or timeout if the upstream Hacker News data source is slow
- max_results out of range (must be 1-10) returns validation error
