How this service works
Machine-payable DDG services for AI agents. Current public live payment rails are x402 multi-chain USDC and direct-crypto auto/manual for public receiving-address families. MPP/Stripe/Tempo is installed but pending live provider env plus penny-settlement proof before any MPP-live advertisement. DDG sells bounded artifacts/results, not raw provider account access.
Output
A JSON response with ok:true plus a collection of matched Hacker News items, typically including story titles, URLs, scores, comment counts, submission timestamps, and author usernames, bounded to the query result set.
Example use cases
Tech trend research on HN
“Search Hacker News for posts about WebAssembly from the last month and show me the most upvoted discussions with their links and comment counts.”
Startup reputation lookup
“Find what Hacker News is saying about Anthropic — pull the top stories and discussions mentioning them so I can see community sentiment.”
Developer job listing discovery
“Search Hacker News for 'who is hiring' posts about remote Rust or Go engineering roles and give me the matching results with URLs.”

Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/hn-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to search Hacker News specifically — useful for developer-focused community sentiment, tech trend discovery, startup reputation research, or finding curated technical discussions. Prefer this over generic web search when the target audience is developers or technical founders and HN community opinion is what matters. The $0.01 USDC micro-payment via x402 makes it suitable for automated agent pipelines that need programmatic, bounded HN search without scraping.
Side effects
- Empty result set if query matches no HN content
- Payment failure or 402 response if USDC balance is insufficient or x402 rails are misconfigured
- Malformed request body returns validation error
- Network timeout if upstream HN search index is slow
- Rate limiting if too many calls are made in quick succession
