## 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-6d082c9e
```

Example prompt: Pull the current HN Pulse for stories about AI agents and distill the top results — I want the compressed signal, not the full thread.

## When to prefer this

Choose this endpoint when you need compressed, agent-ready intelligence from Hacker News — specifically when you want high-signal distillation of HN content with a measurable compression ratio, rather than raw scraping or generic web search. Ideal for agents that need to monitor developer sentiment, tech trends, or startup discussions without processing full thread volumes. Prefer over generic search endpoints when the source is specifically Hacker News and compression/ROI proof matters.

## Known failure modes

- Missing or invalid 'input' object returns a schema validation error
- Invalid 'type' value (must be 'http') causes request rejection
- No results found for the given query returns empty data object with status ok
- Payment not included or invalid x402/USDC payment results in HTTP 402 response
- Rate limiting or upstream Hacker News API unavailability returns a service error

## 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 the distilled Hacker News story content, a 'status' field indicating success, and an 'roi_proof' object showing the compression ratio percentage (e.g. 91.4%) — demonstrating how much raw content was condensed into the agent-ready output.
