## 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 signalsfeed-com-991b0e1b
```

Example prompt: What's the current market sentiment from financial news — is it bullish or bearish, and are we in a risk-on or risk-off environment right now? Include the credibility score on whatever signal you get back.

## When to prefer this

Use this endpoint when you need structured, scored financial news sentiment rather than raw headlines — especially when you need a clear bullish/bearish or risk-on/risk-off classification with a credibility signal attached, and when you want sentiment that captures policy-driven tone shifts (e.g. central bank announcements). Prefer this over general news APIs when the output must be machine-readable and actionable for trading or macro analysis workflows.

## Known failure modes

- No recent news available for the requested topic returns empty or low-confidence signals
- Rate limit exceeded or payment failure via x402 returns 402 Payment Required
- Invalid query parameters return 400 Bad Request
- Upstream news data unavailability may return 503 Service Unavailable
- Credibility scores may be low when news coverage is thin or contradictory
