## 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-news-by-category-4fca9933
```

Example prompt: Pull the latest space news from the open-government news API and give me a summary of each article.

## When to prefer this

Choose this endpoint when you need structured, AI-agent-friendly news summaries sourced specifically from open US government sources (NASA, NOAA, etc.) across a fixed set of science and government categories. It is ideal when you want ready-made attribution and license metadata alongside article summaries. Prefer it over general news APIs when open-government provenance, public-domain licensing, and AI-optimized summaries are important. Not suitable for breaking commercial news, social media trends, or categories outside space, climate, technology, exploration, station, and government.

## Known failure modes

- Invalid or unsupported category value returns an error response
- Payment not provided or x402 handshake fails — request is rejected with 402 Payment Required
- Rate limiting or Cloudflare Worker quota exceeded — 429 or 503 response
- No articles currently available for a valid category — empty articles array
- Network timeout from the upstream government source during article fetching
