## 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 superhighway-news-search-6808c693
```

Example prompt: Find me the latest news articles about the Federal Reserve interest rate decision from the past week — give me up to 10 results.

## When to prefer this

Choose this endpoint when you need real-time or recent news articles specifically — breaking news, current events monitoring, or time-sensitive fact-finding. It is better than general web search endpoints when you want only news sources (not all web pages), and better than static knowledge bases when recency matters. Use over the sibling web search endpoint when you specifically want news articles rather than general organic web results.

## Known failure modes

- Query parameter 'q' missing — returns 400 error
- Payment not provided or insufficient — returns 402 Payment Required
- No results found for query/time combination — returns empty array
- Time filter value not in allowed enum (day/week/month/year) — returns validation error
- Limit exceeds maximum of 20 — returns validation error

## How this service works

Real-time news search for AI agents. Returns recent news articles (title, link, snippet, published date) as JSON from a multi-engine news metasearch. Pay-per-query in USDC via x402 — no signup, no API key. Use for current events, breaking news, monitoring, and time-sensitive facts.

## Output

A JSON array of recent news articles, each containing a title, link, snippet/summary, and published date, sourced from a multi-engine news metasearch. Results are filtered by recency (day, week, month, or year) and capped at the requested limit (1–20, default 5).
