## 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-21db3c51
```

Example prompt: Give me a one-line crypto market snapshot right now — just the sentiment, fear/greed score, and top mover in a single line.

## When to prefer this

Use this endpoint when you need the fastest, cheapest possible snapshot of crypto market conditions — ideal for agents that need a quick sentiment check before making a decision, displaying a market ticker, or routing to a more expensive analysis endpoint only when conditions warrant it. At $0.001 it is the lowest-cost entry point for any crypto market awareness task.

## Known failure modes

- Upstream data source unavailable — may return stale or error response
- Payment not processed — x402 payment required before response is delivered
- Rate limit or network timeout from live data feed

## How this service works

Cheapest endpoint on x402 — $0.001 for a one-line market status. Returns sentiment, fear/greed, and top mover in a single string. Gateway endpoint — try us for a penny.

## Output

A single string like 'Neutral (50) — SOL -1.8%' combining the market sentiment label, numerical fear/greed index score (0-100), and the top-moving token with its percentage change. Also returns parsed fields for fearGreed (number), sentiment (string), and links to sibling endpoints for deeper data.
