## 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 hacker-news-search-via-x402-dc5c1356
```

Example prompt: Search Hacker News for discussions about 'WebAssembly' and show me the top results.

## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call access to Hacker News search without managing API keys or subscriptions. It is ideal for lightweight, sporadic HN lookups within an agent workflow where micropayment via USDC is feasible. Prefer it over scraping or direct Algolia HN API calls when operating in an x402-enabled environment that already handles crypto payment headers.

## Known failure modes

- Missing required 'q' parameter returns an error
- Empty or very broad query may return too many low-relevance results
- Query returning no results yields an empty hits array
- Payment failure (insufficient USDC balance or x402 auth issue) blocks the call
- Rate limiting or server unavailability on the Render-hosted service may return 5xx errors
