## 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 agent-toolkit-web-search-api-8c825f03
```

Example prompt: Search the web for the latest news on quantum computing breakthroughs from the past week, limited to US results, and give me the top 10 ranked pages with their titles, URLs, and snippets.

## When to prefer this

Choose this endpoint when your agent needs live web search results without managing API keys, especially when region-specific or time-filtered SERP data is required. It is ideal for agents that need to retrieve ranked web results programmatically at low cost ($0.003/call) without a Google or Bing API subscription. Prefer it over general scraping endpoints when structured SERP metadata (title, URL, snippet, rank) is the primary need.

## Known failure modes

- Missing required query parameter 'q' returns a validation error
- Invalid region code returns no results or defaults to 'any'
- Invalid time filter value is ignored or causes an error
- Limit value outside 1-10 range may be clamped or rejected
- No results found for highly niche or misspelled queries
