## 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 web-search-via-duckduckgo-scanpay-3553ecfb
```

Example prompt: Search the web for 'best open-source vector databases 2024' and give me the top 5 results with their titles, URLs, and snippets.

## When to prefer this

Prefer this endpoint when you need privacy-respecting web search results without tracking, want clean structured output (title, URL, snippet) without HTML parsing, and need a low-cost ($0.01/call) pay-per-use model. It is ideal for AI agents that need to ground responses in current web information without maintaining a search API subscription. Choose it over scraping or browser automation when lightweight text results are sufficient.

## Known failure modes

- Missing required 'query' parameter returns a validation error
- Limit value outside 1-10 range is rejected or clamped
- DuckDuckGo rate limits or downtime may yield empty results or errors
- Payment failure (non-payment of $0.01 USDC) results in HTTP 402 response
- Very obscure queries may return zero results with an empty results array

## How this service works

Pay-per-call x402 APIs for AI agents: OpenAI-compatible LLM chat, perp funding and arbitrage spreads, crypto prices, gas, FX, Solana SPL mint audit, token price by contract, x402 delivery-receipt verification, web search, clean page extraction, batch tools and deterministic code-security scanning. USDC on Base or Solana, no signup, no API key, from $0.0001 a call.

## Output

A JSON object containing the original query, a product identifier, and an array of result objects each with a title, URL, and snippet. Up to 10 results are returned depending on the limit parameter.
