## 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-hacker-news-top-stories-feed-3a258c11
```

Example prompt: Can you grab the current top stories from Hacker News and give me a compact summary — I need it to fit in my context window without wasting tokens?

## When to prefer this

Choose this endpoint when your AI agent needs current Hacker News top stories but must conserve context window tokens — the built-in compression (claimed ~91% reduction) makes it far more efficient than scraping or calling the HN API directly and parsing raw output. Ideal for agents with tight context budgets or cost-sensitive pipelines. Prefer over raw HN API when token efficiency matters; skip if you need full uncompressed story metadata or comment data.

## Known failure modes

- Payment not received or invalid USDC transaction — 402 Payment Required response
- Upstream Hacker News API unavailable — may return empty data or error status
- Rate limiting if too many requests in a short window
- Malformed query parameter causes input validation failure
- Network timeout to upstream HN source returns partial or null data

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://status.agentdiet.dev settling in USDC on Base.

## Output

Returns a JSON object with a 'data' field containing the top Hacker News stories in compressed form, a 'status' field ('ok' on success), and an 'roi_proof' object showing the compression ratio percentage (e.g. 91.4% compression), demonstrating token savings achieved by the distillation.
