## 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 x402-orthogonal-com-google-search-serper-d807ff7e -d '<json body>'
```

Example prompt: Search Google for 'best open source LLMs 2024' and give me the top 10 organic results in English, filtering to results from the past month.

## When to prefer this

Choose this endpoint when you need broad Google web search results including organic links, knowledge graph summaries, and PAA boxes — especially when you want localization, language filtering, time-bounded results, or pagination. Prefer over specialized search endpoints (Places, Shopping, Maps) when the query is general-purpose or research-oriented rather than local business, product, or map-specific.

## Known failure modes

- Empty or malformed query returns an error or zero results
- Unsupported country/language code returns an error or falls back to defaults
- Requesting more than 100 results returns a validation error
- Time filter string incorrectly formatted returns unexpected results
- Payment failure (x402) prevents the request from being processed
