## 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 multi-source-news-keyword-search-7ad052f4 -d '<json body>'
```

Example prompt: Search news from the last 72 hours for headlines about 'Federal Reserve interest rates' — AND in 'inflation', sort by recency, and filter to English-language sources only.

## When to prefer this

Choose this endpoint when you need to search recent (last 72 hours) news headlines by keyword with Boolean AND logic, quoted phrases, and source/language/date filtering — especially when you need flexible sorting by recency or relevance. Prefer this over general web search when structured headline metadata (source, timestamp) is needed, or when monitoring recent press coverage of specific topics across multiple sources.

## Known failure modes

- No results returned if keywords are too specific or obscure for the 72h window
- Query with unsupported language filter returns empty or error response
- Overly broad queries may return too many loosely-relevant results
- Quoted phrase not found if exact wording differs from indexed headlines
- Rate limit or payment failure if $0.005 USDC per call is not fulfilled

## Output

A list of recent news headlines and associated metadata (source, publish time, relevance score) matching the keyword query from the past 72 hours, sorted by recency or relevance as specified.
