Fetches and distills a compressed intelligence pulse from Hacker News (HN), returning curated trending story data with a high compression ratio for agent consumption.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agentdiet-hn-pulse-hacker-news-story-intelligence-endpoint-ee1b67c9
```

Example prompt: What's trending on Hacker News right now? Give me a distilled summary of the top stories — I want the compressed pulse, not the raw feed.

## When to prefer this

Choose this endpoint when you need a real-time, compressed intelligence pulse from Hacker News specifically — especially when token efficiency matters (91%+ compression) and you want agent-ready distilled output rather than raw RSS or full HTML. Best for recurring tech news monitoring, morning briefings, or trend detection workflows that pay per call in USDC via x402.

## Known failure modes

- No query results if 'query' param is too narrow or HN has no matching recent stories
- HTTP 402 if USDC payment is not provided or insufficient
- Empty data object if HN feed is temporarily unavailable
- Invalid method error if POST is sent with GET-only params
- Malformed response if upstream HN data source is down

## How this service works

15-App Autonomous Business-to-Agent (B2A) API Hub & MCP Suite. Supports Web Distillation, On-Chain Risk, DEX Token Intelligence, B2B Lead Enrichment, Domain OSINT, Email Verification, SEC Filings, GitHub Audits, Prompt Firewall, and native HTTP 402 (x402 Base USDC).

## Output

Returns a JSON object with a 'data' field containing distilled Hacker News story intelligence, a 'status' field ('ok'), and an 'roi_proof' object including a compression_ratio_pct (e.g. 91.4%) indicating how much raw content was condensed for the agent.
