## 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 scanpay-web-search-duckduckgo-479c9192
```

Example prompt: Search the web for 'open source vector databases comparison' and give me the top 5 results with their titles and URLs.

## When to prefer this

Choose this endpoint when you need lightweight, privacy-respecting web search results without API key setup, at a low flat cost of $0.01 per call. It is ideal for AI agents needing real-time web data without Google or Bing API credentials, especially when privacy matters or when already using the ScanPay x402 payment infrastructure.

## Known failure modes

- Missing required 'query' parameter returns a 400/validation error
- Limit out of range (>10 or <1) may be rejected or clamped
- DuckDuckGo backend unavailability may cause 502/503 errors
- Empty query string may return zero results
- Payment failure (x402) blocks access and returns 402 Payment Required
