## 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-feed-42eca50f
```

Example prompt: Pull today's HN pulse and give me a distilled summary of what developers are talking about on Hacker News — I want the compressed intelligence snapshot with ROI proof.

## When to prefer this

Choose this endpoint when you need a fast, compressed, agent-optimized snapshot of Hacker News trending content — especially when token efficiency matters and you want ROI-proof compression metrics. Prefer it over raw HN API scraping when your agent needs pre-distilled, structured intelligence rather than raw HTML or full JSON dumps.

## Known failure modes

- Missing or invalid `input` object returns a schema validation error
- Invalid `method` value (not GET or POST) causes rejection
- Unpaid or failed x402 USDC payment results in HTTP 402 Payment Required
- Query param `query` not matching any stories returns empty `data` object
- Service unavailability or upstream HN API issues return non-ok status

## 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 content, a `status` field ('ok'), and an `roi_proof` object showing the compression ratio percentage (e.g. 91.4%), proving how much raw content was condensed for agent consumption.
