## 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-e135d6b7
```

Example prompt: Pull today's Hacker News pulse for anything trending about AI startups and give me a distilled summary of the top stories.

## When to prefer this

Choose this endpoint when you need a fast, pre-distilled, high-compression snapshot of Hacker News activity — especially when token budget matters and you want signal not raw HTML. It's ideal for agents monitoring tech trends, startup news, or developer community sentiment without scraping HN directly. Prefer it over generic web scrapers when you want structured, compressed output with ROI proof and pay-per-use micropayment pricing.

## Known failure modes

- Payment not received via x402 — returns HTTP 402 requiring USDC micropayment
- Invalid query parameter type — returns schema validation error
- HN upstream unavailable — may return empty data or error status
- Rate limit exceeded — returns throttle or error response
- Malformed input object missing required 'type' or 'method' fields — returns 400

## 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 distilled Hacker News story data under a 'data' key, a status field ('ok'), and an roi_proof object containing a compression_ratio_pct (e.g. 91.4%) indicating how much the raw content was compressed into the signal delivered.
