## 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-7bb0dc82
```

Example prompt: Can you pull today's Hacker News pulse and give me a distilled summary of what's trending in tech — I want the compressed highlights, not the full firehose.

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.01 USDC) distilled summary of Hacker News without parsing raw feeds yourself. It is ideal for agents that need a compressed, high-signal tech intelligence brief rather than raw HTML or RSS. Prefer it over general web scrapers when you specifically want HN content with built-in compression and ROI metrics.

## Known failure modes

- Missing or malformed 'input' object returns a validation error
- Invalid 'type' value (must be 'http') causes schema rejection
- Payment failure via x402/HTTP 402 blocks access if USDC balance is insufficient
- Upstream HN data unavailability may result in empty 'data' payload with status still 'ok'
- Unsupported method value outside GET/POST enum causes input rejection

## 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 HN content, a 'status' field confirming success ('ok'), and an 'roi_proof' object showing the compression_ratio_pct (e.g. 91.4%) — demonstrating how much raw content was condensed into the response.
