## 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-fe2abb01
```

Example prompt: Pull the current Hacker News pulse and give me a distilled summary of what the tech community is buzzing about today — I want the high-signal stuff, compressed and ready to scan.

## When to prefer this

Choose this endpoint when you need a machine-ready, compressed summary of current Hacker News activity without scraping HN yourself. It is especially useful when token budget matters (91%+ compression ratio), when you want structured JSON output rather than raw HTML, and when you need pay-per-call pricing via USDC with no subscription overhead.

## Known failure modes

- Invalid or missing 'type' or 'method' fields in input returns a 400-level error
- Service unavailable or upstream HN fetch failure returns error status
- Payment not completed (HTTP 402) blocks access until x402 USDC payment is made
- Empty or no query param may return generic top-level HN content rather than filtered results

## 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 ('ok'), and an 'roi_proof' object showing the compression_ratio_pct (e.g. 91.4%), indicating how much the raw content was condensed.
