# SiteCheck Agent Intel & Dev — Web Search (DuckDuckGo)

> SiteCheck Agent Intel & Dev — Web Search (DuckDuckGo) is a paid API for AI agents from api.fadeandco.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-29).

## 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 sitecheck-agent-intel-dev-web-search-duckduckgo-4c53fc69
```

Example prompt: Search the web for 'best practices for rate limiting REST APIs' and give me the top 5 results with titles, URLs, and snippets.

## When to prefer this

Choose this endpoint when you need quick, ad-free web search results (titles, URLs, snippets) sourced from DuckDuckGo without requiring an API key or paying for a premium search API. It is ideal for lightweight research, link discovery, and general information retrieval by AI agents. Prefer it over paid search APIs (Google Custom Search, Bing Search API) when cost is a concern and DuckDuckGo's coverage is sufficient. Note that relevance scores are not available, and empty-result pages are possible.

## Known failure modes

- DuckDuckGo returns empty HTML page even after retries — results array is empty with a 'note' field indicating no results
- Query string shorter than 2 or longer than 200 characters — likely rejected or ignored
- Limit parameter outside 1-10 range may default to 5 or be clamped
- Rate limiting or upstream DuckDuckGo blocking — may return empty results
- Network timeout to DuckDuckGo's public HTML endpoint

## How this service works

Web search via DuckDuckGo's public HTML results page: ranked titles, direct result URLs and snippets, no ads. No relevance score (DuckDuckGo does not publish one). DuckDuckGo often answers with an empty page; the tool retries, and if it still gets none the list is empty and 'note' says so.

## Output

A JSON object containing the original query, the DuckDuckGo source URL, a timestamp, and an array of results — each with a rank (integer), page title, direct URL, and text snippet. If DuckDuckGo returns an empty page after retries, the results array is empty and a 'note' field explains why.
