## 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 x402-web-search-d4a2a386
```

Example prompt: Search the web for the latest news about quantum computing breakthroughs and give me up to 10 results with titles, URLs, and summaries.

## When to prefer this

Choose this endpoint when you need real-time or recent web search results aggregated from multiple search engines, especially for news or image queries where freshness matters. Prefer it over static knowledge bases when you need live URLs and snippets. Its multi-engine aggregation via SearXNG provides broader coverage than a single search provider, and the per-call micropayment model makes it cost-effective for occasional lookups.

## Known failure modes

- Empty results if query matches nothing in the SearXNG index
- Missing published dates for results that don't carry date metadata
- Category enum mismatch causes a 400-level error
- max_results exceeds 10 causes validation failure
- SearXNG instance unavailable returns a 5xx error
- Payment not submitted or insufficient USDC balance causes 402 rejection

## How this service works

Web search that returns structured SERP results as JSON. Runs on a dedicated SearXNG instance aggregating multiple engines, so there is no per-engine API key, quota or HTML scraping to manage. Each result carries title, URL, snippet, the source engine and a published date where available. Choose general web, news, or image results, up to 10 per call. Use it to ground an answer in current web sources, research a topic, or monitor news on a query.

## Output

Returns up to 10 search results, each containing a title, URL, snippet/description, the source search engine that returned it, and a published date where available. Results vary by category: general web pages, news articles, or image links depending on the category parameter.
