Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 three-ws-news-pulse-ticker-news-sentiment-scanner-c9cbdac7
```

Example prompt: Pull the news pulse for BTC over the last 24 hours — I want to see mention counts, whether coverage is accelerating or slowing down, and a breakdown of positive vs negative sentiment across headlines.

## When to prefer this

Choose this endpoint when you need a quick, structured snapshot of news volume, sentiment, and velocity for a specific financial ticker — especially useful for crypto or stock research workflows where you want headline-level data plus quantified sentiment without building your own news scraper. Best suited for single-ticker lookups over short windows (1–72 hours). If you need broader market news without ticker-specific filtering or require real-time streaming, consider alternatives.

## Known failure modes

- Missing required 'ticker' parameter returns validation error
- Ticker not found in news sources returns zero mentions with empty headlines array
- hours parameter out of range (less than 1 or greater than 72) returns validation error
- Payment not fulfilled (x402) results in 402 Payment Required before data is returned
- Upstream news aggregation service unavailable returns 5xx error
