## 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 hergert-synthora-web-search-49117f3b -d '<json body>'
```

Example prompt: Search the web for the latest x402 protocol specification, return up to 10 results, and also pull the full content of the top result as markdown.

## When to prefer this

Choose this endpoint when you need both web search results and optional deep page extraction in a single paid call via x402 micropayment. Prefer it over generic search APIs when you want DuckDuckGo-backed results with clean markdown extraction of the top result, especially for agent workflows that need source text, not just snippets. Suitable for real-time research, fact-checking, and document retrieval tasks where freshness matters.

## Known failure modes

- Query returns zero results if too niche or malformed
- Extraction fails if top URL blocks scraping or has no extractable content
- max_results out of range (must be 1–20) causes validation error
- Network timeout if upstream DuckDuckGo or target page is slow
- ok: false returned with error description for upstream failures

## Output

A JSON object containing: a list of up to 20 search results (each with URL, title, and snippet), the result count, query echo, source label, and elapsed time in milliseconds.
