## 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 quantaflow-hacker-news-proxy-x402-5f15fd72 -d '<json body>'
```

Example prompt: Can you fetch the current top 10 stories from Hacker News, including their titles and scores?

## When to prefer this

Use this endpoint when your agent needs programmatic, pay-per-use access to Hacker News data via an x402 micropayment flow without managing a separate API key; ideal for web3-native agents that already handle USDC payments on-chain.

## Known failure modes

- Payment failure if insufficient USDC balance — returns 402 Payment Required
- Invalid path resulting in a 404 from the upstream Hacker News API
- Malformed query parameters causing upstream errors
- Rate limiting or downtime on the underlying Hacker News API
- Network timeout on the Vercel proxy layer

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

The raw upstream Hacker News API response is passed through as-is after successful micropayment, including story lists, item details, comments, or user data depending on the path queried.
