## 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 agentdata-web-search-4bd61fdd -d '<json body>'
```

Example prompt: Search the web for 'best open-source LLMs in 2025' and give me the top 5 results with titles, URLs, and snippets — if there's a direct answer box, include that too.

## When to prefer this

Choose this endpoint when your agent needs live web search results without setting up an account or API key, and cost-per-call matters (at $0.008 USDC it is priced below typical x402 market rates). Ideal for agents that need compact, LLM-ready JSON rather than raw HTML, and for sporadic or low-volume lookups where a subscription model is wasteful. Prefer it over scraping solutions when you need structured snippets, direct answers, and knowledge graph data in one call.

## Known failure modes

- Query string missing — returns 400 bad request
- Payment not sent or insufficient USDC — returns 402 payment required
- num parameter outside 1-10 range — may return error or default behavior
- Invalid country or language code — may return unexpected locale results
- Upstream search provider unavailable — returns 5xx error
- No results found for niche query — returns valid empty results array

## How this service works

Google-quality web search for AI agents at $0.004 per search — the lowest x402 rate for full search results. Send a query, get back compact JSON built for LLM consumption: top organic results (position, title, url, snippet), the direct answer when one exists, a trimmed knowledge graph and related searches. Tune with num (1-10 results), country and language (2-letter codes). Zero results is a valid, honest answer. Pay per call in USDC, no account, no API key.

## Output

A compact JSON object containing: an array of organic results (each with position, title, URL, and snippet), a direct answer string when one exists, a trimmed knowledge graph with key facts, and a list of related searches. Zero results is returned as an empty array rather than an error.
