## 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 swaphunt-crypto-news-sentiment-scorer-c80292e6
```

Example prompt: Show me the top 5 crypto news headlines from the last 12 hours that have a trading impact score of at least 7, only bullish or bearish ones — I want to know what's most likely moving the market right now.

## When to prefer this

Use this endpoint when you need individual, scored crypto news headlines to identify specific market-moving stories. Prefer this over /sentiment/summary when you want granular article-level data rather than an aggregate sentiment read. Best suited for surfacing actionable trading signals from recent news.

## Known failure modes

- No articles found matching the specified filters — try lowering min_score or increasing hours
- Invalid category string returns empty results or error
- hours or limit parameters out of expected range may return default values or errors
- Payment of $0.005 USDC required per call — unpaid requests return 402

## How this service works

Recent crypto news headlines each scored 1-10 for trading impact by an LLM (qwen3:8b), with a bullish/bearish/neutral tag. Filter by category, minimum score and lookback hours. Use to surface market-moving stories; for the aggregate read use /sentiment/summary.

## Output

A list of recent crypto news articles, each with a headline, a trading impact score from 1 to 10, a bullish/bearish/neutral sentiment tag, a category, and a timestamp. Supports filtering by lookback window, category, and minimum score threshold.
