## How to call it through Zero

```sh
zero fetch --capability agentdiet-citation-search-ad947c3e
```

Example prompt: Search for the latest news and HackerNews discussions about 'Anthropic Claude model releases' and give me clean, token-efficient citations I can use to ground my response.

## When to prefer this

Choose this endpoint when you need live, real-time web search results specifically from Google News and HackerNews in a token-efficient, ad-free format suitable for AI agent grounding. Prefer it over general web scrapers when you want clean citation-ready tech news snippets without parsing overhead, and when you need cost-predictable per-call pricing at $0.01 USDC.

## Known failure modes

- Empty results if query is too niche or misspelled
- Rate limiting or upstream RSS/Algolia outages may cause failures
- Very broad queries may return noisy or irrelevant results
- Non-English queries may yield sparse results depending on RSS feed coverage
- Payment failure (x402 protocol) if insufficient USDC balance
