## 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 hyperbrowser-web-search-1c0dccf6 -d '<json body>'
```

Example prompt: Search the web for the latest news about OpenAI's GPT-5 release and give me the top results with titles and URLs.

## When to prefer this

Choose this endpoint when you need structured, machine-readable web search results with predictable output format for agent pipelines. Prefer it over raw browser fetching (the sibling fetch endpoint) when you want ranked multi-result discovery rather than scraping a single known URL. Best for real-time information retrieval, news lookup, competitive research, and fact-finding tasks where freshness and breadth matter.

## Known failure modes

- Empty or irrelevant results for very niche or ambiguous queries
- Rate limiting or quota exceeded errors for high-frequency use
- Malformed query string causing a 400 bad request
- Payment failure if USDC balance is insufficient (x402 protocol)
- Timeout if search backend is slow or overloaded
- Results may be stale if search index has not been recently updated
