## 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 vibe-springs-crypto-news-feed-with-sentiment-analysis-b2846234
```

## When to prefer this

Choose this endpoint when you need real-time cryptocurrency news with sentiment scoring baked in, especially when you want to filter by mood (bullish/bearish) or cluster related stories across multiple outlets. Prefer it over generic news APIs when crypto-specific topic filtering and sentiment bands are required in a single call.

## Known failure modes

- Invalid 'since' format returns a 400 error — use ISO timestamp or shorthands like '1h', '6h', '24h'
- minSentiment or maxSentiment out of range (-1 to 1) returns a 400 validation error
- limit exceeding 50 returns a 400 error
- No articles matching the filters returns an empty result set
- Payment failure (x402) returns a 402 response requiring valid USDC payment
- Topic keyword with no matching articles returns empty array
