## 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-pulse-35b35bfa
```

Example prompt: What's the current news pulse for 'bitcoin,etf' — give me the volume velocity and sentiment over the last 24h?

## When to prefer this

Use this endpoint when you need real-time or near-real-time aggregated news metrics — coverage volume, velocity, and sentiment — for specific crypto keywords over defined short timeframes. Prefer this over raw news feeds when you need pre-computed analytics rather than individual articles. Best suited for monitoring media momentum, detecting news spikes, or scoring sentiment around specific tokens or crypto topics.

## Known failure modes

- Missing required 'topic' query parameter returns a 400 error
- Invalid window value (not '1h', '6h', or '24h') may return an error or default behavior
- No news found for obscure topic returns empty or zero-value metrics
- Payment not processed (x402) results in 402 Payment Required response
- Rate limiting or quota exceeded returns a 429 error

## How this service works

Synthesized news coverage metrics, volume velocity indicators, and sentiment aggregates for targeted crypto topics over sliding window timeframes.

## Output

Returns synthesized metrics including news coverage volume, velocity of news acceleration, and sentiment aggregates (positive/negative/neutral signals) for the specified crypto topic keywords over the requested sliding window timeframe (1h, 6h, or 24h).
