## 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 web-search-via-serper-google-results-c95c53be
```

Example prompt: Search Google for 'best JavaScript frameworks 2024' and show me the top organic results, answer box, and any knowledge graph info — use English results targeted at the US.

## When to prefer this

Choose this endpoint when you need real, live Google organic search results cheaply — especially when cost matters and you want the top 10 results plus answer box and knowledge graph in one call. It is cheaper than alternatives like Exa /search on the x402 network and delivers genuine Google SERP data via Serper. Prefer it for general web search, quick fact lookups, or when you need structured Google result data with optional locale targeting.

## Known failure modes

- Missing or empty query parameter returns no results or an error
- Invalid gl/hl locale codes may return unexpected regional results
- No answer box or knowledge graph returned if Google does not feature one for the query
- Rate limiting or payment failure if USDC balance is insufficient
- Query returning 0 organic results for very obscure or malformed searches
