Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-intelligent-web-search-ae6b2965 -d '<json body>'
```

Example prompt: Search the web for the latest research on transformer architectures in 2024 — expand the query into multiple angles to improve coverage, and only pull results from arxiv.org and github.com.

## When to prefer this

Choose this endpoint when you need live web search with intelligent query expansion (fan-out) to maximize recall across different phrasings. Prefer it over generic search APIs when you want fine-grained domain control (whitelisting or blacklisting specific sites) or need to ensure freshness of results. Especially valuable for research agents that need comprehensive, multi-angle coverage of a topic from authoritative or curated domains.

## Known failure modes

- Empty query string returns an error or zero results
- Invalid domain format in include_domains or exclude_domains may be silently ignored or cause an error
- Overly restrictive domain filters returning zero results
- Insufficient credits causing payment failure (x402 payment required)
- Freshness filter with no recent content returns few or zero results
- Query fanout may increase latency and credit consumption

## How this service works

Performs an intelligent web search. Costs 1 credit per returned result.

## Output

A list of web search results, each containing a URL, page title, and snippet or summary. The number of results determines credit cost (1 credit per returned result). Results may be filtered by domain and recency, and can cover multiple query angles if queryFanout is enabled.
