## 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-7b6780c5
```

Example prompt: Can you find me the top 10 news stories about artificial intelligence regulation from the past week?

## When to prefer this

Use this endpoint when you need fresh, time-bounded news results from the live web rather than static or cached content. Prefer this over general web search when the user explicitly wants news articles or recent coverage of a topic. The recency filter (day/week/month/year) makes it especially useful for monitoring breaking news or tracking a story over a specific time window. Pay-per-call pricing at $0.001 USDC makes it economical for high-frequency agent workflows.

## Known failure modes

- Missing required 'q' query parameter returns a validation error
- Invalid 'time' enum value (e.g. 'hour') returns a 400 error
- Limit out of range (below 1 or above 20) returns a 422 validation error
- Payment not provided or insufficient results in 402 Payment Required
- No news results found for obscure or very recent queries may return empty result set
- Network or upstream search provider outage returns 5xx error

## How this service works

## Output
