How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.
Output
A JSON object with a 'data' field containing velocity-ranked HackerNews stories or topics, a 'status' field ('ok'), and a 'roi_proof' object showing the compression_ratio_pct (e.g. 91.4%), indicating how much raw HN data was distilled into the response.
Example use cases
Morning tech briefing for founders
“Give me a quick rundown of what's blowing up on Hacker News this morning — I want the stories gaining the most velocity, especially anything in AI or developer tools.”
Competitive intelligence on emerging topics
“Can you check the HackerNews velocity radar for anything trending around large language models or open-source infrastructure right now?”
Content team trend-spotting
“We're planning our editorial calendar — what topics are currently accelerating fast on Hacker News that our audience of software developers would care about?”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/hackernews-velocity-radar?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real-time, velocity-weighted view of HackerNews rather than a raw ranked list — particularly useful for trend detection, editorial planning, or competitive intelligence where recency and momentum matter more than absolute upvote count. Prefer it over generic HN APIs when you want pre-compressed, high-signal output rather than raw data you'd need to process yourself.
Side effects
- Payment not settled — x402 payment in USDC on Base required before data is returned
- Query returns no results — generic or misspelled query may yield empty data
- Service unavailable — upstream HackerNews data source unreachable
- Invalid input schema — missing required 'type' or 'method' fields returns a 400-level error
