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-96a676ab
```

Example prompt: Pull the latest Hacker News pulse and give me a compressed digest of what's trending in tech right now — I want the key stories distilled down so I'm not reading through everything myself.

## When to prefer this

Choose this endpoint when you need a fast, compressed, agent-optimized digest of Hacker News trending content without parsing the full HN feed yourself. It is especially useful for autonomous agents doing daily tech briefings, trend monitoring, or competitive intelligence gathering, where token efficiency matters and the compression ratio proof provides verifiable ROI. Prefer this over raw HN API calls when you want pre-distilled, structured output ready for downstream reasoning.

## Known failure modes

- Missing or invalid 'input' object returns a 400-style validation error
- Invalid method enum value (not GET or POST) causes request rejection
- Empty or malformed query param may return empty data with status ok
- Payment not fulfilled via x402/HTTP 402 results in a 402 Payment Required response before data is returned
- Service unavailability or upstream HN API issues may return error status

## 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 stories or pulse signals, a 'status' field indicating success, and an 'roi_proof' object showing the compression_ratio_pct (e.g. 91.4%), confirming how much raw content was condensed into agent-ready output.
