## 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 google-serp-api-968a726c -d '<json body>'
```

Example prompt: Search Google for 'best electric SUVs 2025' in the US, in English, showing the top 5 results — include organic results, any answer box or knowledge graph, and page summaries.

## When to prefer this

Choose this endpoint when you need rich, structured Google SERP data beyond plain organic links — specifically when you need domain authority scores, result-type labels, knowledge graph, answer boxes, People Also Ask, local pack, or page summaries in a single call. It is 3x cheaper than comparable SERP APIs and supports geo-targeting by country, language, and city. Prefer it over generic web search endpoints when SEO analysis, local search, or full SERP feature extraction is the goal.

## Known failure modes

- Invalid or missing query returns 400 error
- Unsupported country/language code may return default US/en results
- numResults outside 1-10 range may be clamped or rejected
- Private mode queries bypass cache and may be slower
- Freshness filter may reduce result count for narrow time windows
- Rate limiting or payment failure returns 402 or 429 error
