## 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 latest-news-api-open-government-6a1403c8
```

Example prompt: Pull the latest open-government news headlines across space, climate, and technology — I need structured summaries with source links I can trust.

## When to prefer this

Choose this endpoint when you need structured, AI-agent-ready news from open U.S. government sources (NASA, federal agencies) with proper attribution and license metadata. It is ideal for pipelines that require legally clear public-domain content with source_url attribution. Prefer it over general news APIs when the domain must be restricted to official government or public-sector sources across space, climate, technology, exploration, station, or government categories.

## Known failure modes

- Payment not completed (x402 payment required — HTTP 402 returned if USDC micropayment not sent)
- Invalid or missing category parameter returns all categories by default
- Network/edge timeout from Cloudflare Workers may return 5xx
- Empty article list if no new articles have been fetched for a category
- Truncated summaries if upstream government sources are unavailable
