## 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 websearch-hergertsynthora-com-web-search-26cac590 -d '<json body>'
```

Example prompt: Search the web for 'best practices for securing Redis in production 2024' and give me the top 5 results — and also pull the main content from the top result so I can read it directly.

## When to prefer this

Choose this endpoint when an AI agent needs live, unkeyless web search without setting up Google, Bing, or Serper API credentials. It is ideal when you want both ranked results and the ability to read page content in one call (via answer_extract), avoiding a separate scraping step. Prefer it over self-hosted search when you want resilient multi-source fallback behavior and SSRF hardening out of the box.

## Known failure modes

- All search sources (DuckDuckGo + SearXNG) temporarily unavailable — though automatic fallback between sources minimizes this
- Query too vague or empty — returns no meaningful results
- Top result page blocks scraping — answer_extract may be empty or partial
- SSRF guard triggers on certain internal/localhost-like URLs in extract mode
- Rate limiting or timeout on slow-loading pages when extract=true

## How this service works

Keyless web search for AI agents. Give it a natural-language query and it returns ranked organic results (title, url, snippet) drawn from live multi-source search (DuckDuckGo HTML/Lite plus public SearXNG instances, with automatic fallback so it never returns empty when one source flakes). Optionally it also fetches the top result and extracts the main content as clean, token-budgeted markdown (answer_extract), so an agent can read the page without running its own crawler, browser or scraper. Use it to answer real-world questions, gather fresh facts, research a topic, find documentation or check what a site says, without maintaining a search index or paying for Google/Bing/Serper API keys. Resilient (short timeouts, multi-source), SSRF-hardened, 0.005 USDC on Base.

## Output

Returns a ranked list of organic search results (each with title, URL, and snippet), plus optionally an answer_extract field containing the main content of the top result as clean, token-budgeted markdown scraped from the live page.
