## 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 hubvibe-web-research-cited-answer-from-live-search-0167075c -d '<json body>'
```

Example prompt: Search the web and find out what the current status of the EU AI Act implementation is — give me a cited answer with up to 4 sources so I can see where each claim comes from.

## When to prefer this

Choose this endpoint when you need a grounded, cited answer to an open-ended question using current web data — especially when the user wants to know where each claim comes from. Prefer it over a simple search endpoint when citation provenance matters. Use it over a static knowledge base when freshness is required (news, regulations, prices, current events). Best for 1–4 source synthesis; not suited for deep multi-source research across dozens of URLs.

## Known failure modes

- Question is too vague to produce meaningful search results — returns a low-quality or empty answer
- max_sources out of range (must be 1–4) — may return a validation error
- Live search yields no relevant results for niche or very recent queries
- Rate-limited or payment failure — endpoint returns 402 or rejection
- Network timeout if source pages are slow to load during synthesis

## How this service works

Deep web research with citations: search the live web for your question, read the top sources in full, and get a written answer with every claim tied to a numbered source. Use it when an agent needs a sourced answer, not a list of links. Input: question; optional max_sources. Quick answer with links: search.web.

## Output

A natural-language answer to the question, with every factual claim annotated by a numbered source reference (e.g. [1], [2]). Also returns the list of source URLs or citations used, tied to the numbered references in the answer.
