## 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 web-search-with-synthesized-answer-ba6138f1
```

Example prompt: Search the web for the latest news on OpenAI's GPT-5 release and give me a synthesized summary plus the top 5 sources.

## When to prefer this

Choose this endpoint when an AI agent needs to access information published after its training cutoff — recent news, current prices, live documentation, software releases, or incidents. It is preferable over static knowledge bases or RAG pipelines when freshness is paramount. The built-in answer synthesis saves an extra LLM call compared to raw search APIs that return only URLs and snippets.

## Known failure modes

- Empty or vague query returns low-relevance results or empty result set
- maxResults out of range (outside 1-20) may cause a validation error
- No results found for very niche or malformed queries
- Rate limiting or payment failure if USDC balance is insufficient ($0.01 per call)
- Network timeout if the live web crawl takes too long for obscure queries

## How this service works

Search the live web from an agent that has no browser: pass query= and get back ranked results (title, URL, snippet, relevance score) plus a synthesized one-paragraph answer over them. maxResults=1..20 (default 5); includeAnswer=false to skip the summary and take sources only. The step before reasoning about anything that happened after the model's training cutoff — prices, releases, incidents, docs. Nothing crypto about it.

## Output

Returns up to 20 ranked web results each containing a title, URL, snippet, and relevance score. When includeAnswer is true (the default), also returns a synthesized one-paragraph answer generated over the top results. Response is JSON structured with results array and optional answer field.
