## 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 mdataaccess-web-search-6aba476d
```

Example prompt: Search the web for the latest developments in quantum computing and return the top 5 results with titles, URLs, and summaries.

## When to prefer this

Choose this endpoint when an agent needs live, up-to-date web search results with structured output tailored for autonomous agent consumption. It is especially useful when training-data cutoffs make LLM knowledge insufficient, or when real-time information (news, prices, recent events) is required. Prefer it over raw HTTP scraping when you need a ranked list of relevant URLs and snippets rather than the full content of a single page.

## Known failure modes

- Missing required query parameter 'q' returns a 400 Bad Request
- num_results exceeding maximum of 10 returns a validation error
- Payment failure or missing x402 payment header results in a 402 Payment Required response
- Queries with no matching web results return an empty results array
- Rate limiting or quota exhaustion may return a 429 Too Many Requests error
- Network timeouts for slow upstream search providers may return a 503 error

## How this service works

Search the web. Returns structured search results suitable for autonomous agents.

## Output

Returns a structured JSON object containing the original query, the provider name, and an array of search results. Each result typically includes a title, URL, and snippet/summary suitable for agent reasoning and downstream processing.
