## 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 jmt-x402-news-briefing-a6d5b904 -d '<json body>'
```

Example prompt: Give me a full news briefing on NVIDIA — current sentiment, key takeaways, and anything I should be watching closely.

## When to prefer this

Choose this endpoint when you need a fast, structured, multi-angle news digest on a specific topic, company, asset, or event — especially when you want LLM synthesis plus sentiment and watch-items rather than raw search snippets alone. Prefer it over generic search endpoints when you want an editorially shaped briefing with deduplication and source attribution.

## Known failure modes

- Empty or missing topic field returns a validation error
- Topic too vague may yield low-signal results with generic synthesis
- Payment not included or rejected results in a 402 Payment Required response
- Upstream web search temporarily unavailable causes partial or failed briefing
- LLM synthesis timeout may result in incomplete output

## How this service works

## Output

A structured news briefing containing: deduplicated current web results with source links, a concise LLM-synthesized narrative, an overall sentiment overview, bullet-point key takeaways, and flagged watch items worth monitoring — all grounded in live web data.
