## 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 alpha-palmvox-com-ee5daac9
```

Example prompt: What's the latest breaking crypto news headline right now, and is it bullish or bearish — what's the market impact?

## When to prefer this

Use this endpoint when you need a fast, single-call snapshot of the most impactful crypto news headline plus its sentiment and market impact — ideal for AI agents that need a quick market pulse without ingesting a full news feed. Prefer this over raw news APIs when pre-computed sentiment and impact scoring is needed out of the box.

## Known failure modes

- No recent news available — stale or empty response if data pipeline is lagging beyond 2-hour cycle
- Payment required (402) if x402 payment header is missing or USDC balance is insufficient
- Rate limiting or service unavailability returning 5xx errors
- Partial response if sentiment model fails to classify the headline
