# x402 Web Search – Core Search Endpoint

> x402 Web Search – Core Search Endpoint is a paid API for AI agents from search.cyberwarex.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-30).

Performs a keyword web search and returns up to 10 results with URLs, titles, published dates, and page text for the top 5, billed per successful call via x402.

## 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-core-search-endpoint-a0624c59
```

Example prompt: Search the web for the latest developments in quantum computing and give me up to 10 results, including the page text from the top articles, but exclude results from Wikipedia.

## When to prefer this

Choose this endpoint when you need standard keyword-based web search results with optional page text extraction in a single call, without managing API keys. It is ideal for agents already using a neural-search SDK that can point its base URL at https://search.cyberwarex.com/v1. Prefer it over alternatives when you want Google-grade result quality on a pay-per-successful-call model (no charge for empty results) and need domain inclusion/exclusion filtering. If you need a plain-language answer rather than raw results, or need academic paper search, use the sibling endpoints instead.

## Known failure modes

- Empty results array returned when query matches no indexed pages — no charge incurred
- Payment failure or x402 handshake error if the calling client does not support the x402 micropayment protocol
- Query parameter missing or too short (minLength:1) returns a validation error
- numResults exceeds maximum of 10, causing a schema validation rejection
- includeDomains or excludeDomains contains malformed domain strings, potentially causing unexpected filtering
- Rate limiting or upstream search engine unavailability may return a 503 or timeout

## How this service works

Drop-in web search API: POST the common search body (query, numResults, includeDomains, excludeDomains, contents.text) and get results with id, url, title, publishedDate and page text. Point an existing neural-search SDK base URL at https://search.cyberwarex.com/v1, no key. Keyword engine, Google-grade results on paid calls. Up to 10 links, text for the top 5. No results = not charged.

## Output

A JSON array of up to 10 search results, each containing a unique ID, URL, title, published date, and (for the top 5) extracted page text. Also includes a request ID, resolved search type, and a cost breakdown object showing what was charged for the call. Returns an empty results array (and no charge) if no results are found.
