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-intelligence-distillation-c761b84b
```

Example prompt: Pull the HN Pulse feed for stories about AI agents and give me the distilled highlights — I want the compressed, high-signal summary of what the Hacker News community is currently discussing on that topic.

## When to prefer this

Choose this endpoint when you need a fast, compressed, high-signal digest of current Hacker News content — especially when raw HN volume is too noisy for direct consumption by an agent. Ideal for trend monitoring, developer sentiment analysis, or startup intelligence workflows that need distilled tech community signals at low cost ($0.01 USDC per call).

## Known failure modes

- Missing or invalid 'input' object returns validation error
- Unsupported HTTP method (not GET or POST) returns enum error
- Downstream HN source unavailable causes empty or error data response
- Payment failure via x402/USDC results in HTTP 402 blocking the request
- Query param 'query' not provided may return a generic rather than topic-specific pulse

## 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 content, a 'status' field ('ok'), and an 'roi_proof' object showing the compression ratio percentage (e.g. 91.4%), demonstrating how much raw content was compressed into the summary.
