## 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 arch-tools-web-search-7c8d7334 -d '<json body>'
```

Example prompt: Search the web for the latest news about OpenAI's GPT-5 release and give me the top 5 results.

## When to prefer this

Choose this endpoint when your agent needs live, up-to-date web search results that go beyond static training data — especially for recent events, news, or rapidly changing information. It is well-suited for workflows that need to retrieve URLs and snippets for a query programmatically and integrate with other Arch Tools endpoints (e.g. extract-page or extract-pdf for follow-up content extraction). Prefer this over static knowledge bases when freshness matters.

## Known failure modes

- Empty or vague query returns no useful results
- Query string is missing — returns 400 validation error
- Rate limiting or quota exhaustion causing failures
- Payment not processed or USDC balance insufficient — returns 402
- External search backend unavailable causing 5xx errors
- Limit parameter set to 0 or negative integer may cause unexpected behavior

## How this service works

Web search with structured results - title, URL and snippet - ready for agent consumption. Fresh results in one POST. Pay per call with USDC (x402) or credits - archtools.dev

## Output

A JSON object containing a list of web search results, each likely including a title, URL, and snippet/description for the matching page, ranked by relevance to the query.
