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-distillation-endpoint-32475639
```

Example prompt: Can you pull today's Hacker News pulse and distill it down — I want to know what the tech community is buzzing about right now, especially anything related to AI or developer tools?

## When to prefer this

Choose this endpoint when you need a pre-digested, highly compressed intelligence feed from Hacker News rather than scraping raw HN yourself. It is ideal for agents that need to monitor tech community sentiment, trending topics, or developer discourse without spending tokens on raw HTML parsing. The built-in compression ratio proof makes it easy to audit efficiency in agentic pipelines. Prefer it over generic web scrapers when the target source is specifically Hacker News and token/cost efficiency matters.

## Known failure modes

- Missing or invalid 'input' object returns a 400 validation error
- Payment not included or insufficient USDC results in HTTP 402 payment required
- Query parameter malformed or unsupported type causes rejection
- Upstream Hacker News data unavailable causes 503 or empty data response
- Rate limiting or quota exceeded may return 429

## 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 content, a 'status' field indicating success, and an 'roi_proof' object showing the compression_ratio_pct (e.g. 91.4%), demonstrating how much the raw content was compressed into the agent-ready payload.
