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 sift-web-tools-ai-web-search-e7500d19
```

Example prompt: Search the web for when Python 3.14 was released and give me an answer with up to 10 sources.

## When to prefer this

Choose this endpoint when you need a grounded, citation-backed answer to a factual or current-events question and want a synthesized response rather than raw HTML. It is ideal for agents that need live web data without scraping individual pages manually. Prefer it over /v1/fetch or /v1/ask when you do not already have a specific URL in mind and need broad web coverage. At $0.06 per call with pay-only-on-success pricing via x402 on Base, it suits cost-sensitive agent pipelines where reliability matters.

## Known failure modes

- Query shorter than 2 or longer than 400 characters returns a validation error
- No relevant web sources found returns an empty sources array or low-confidence answer
- Payment failure via x402 (insufficient USDC balance) results in no charge and no response
- Rate limiting or upstream search provider outage returns a non-200 error (no charge applied)
- Highly ambiguous or nonsensical queries may return a generic or unhelpful answer

## How this service works

Web search with a grounded answer and source links (Google Search). Searches the live web with Google Search and returns a concise factual answer plus the source pages (title and real URL) and the queries used. Good for current facts, prices, news and docs.

## Output

A JSON object containing a synthesized natural-language answer to the query and an array of source objects, each with a URL and title, drawn from up to 15 web pages. The answer is grounded in the retrieved sources with supporting quotes where available.
