## 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 orthogonal-web-search-3fd13b00 -d '<json body>'
```

## When to prefer this

Choose this endpoint when you need to retrieve live web documents and their content for a given query, especially when you require both the URL and textual content of matching pages. Prefer this over static knowledge bases when freshness and real-time web coverage matter. It is well-suited for research, news retrieval, and competitive intelligence tasks where programmatic search results are needed.

## Known failure modes

- Empty result set if the query is too niche or misspelled
- Rate limiting or payment failure if USDC balance is insufficient
- Partial results if fewer matching documents exist than max_results requested
- Timeout if the web search takes too long to respond
- Malformed query returns an error or empty results

## How this service works
