## 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 crypto-market-snapshot-pack-307851ee
```

Example prompt: Give me today's crypto market snapshot — top 50 coins by market cap with their prices, 24-hour changes, and volume, plus the last 30 days of Fear & Greed index data.

## When to prefer this

Choose this endpoint when you need a comprehensive, pre-aggregated daily crypto market overview covering both price/volume data for the top 50 coins and sentiment history (Fear & Greed) in a single call. Ideal for dashboards, morning briefings, or sentiment-aware trading signals where a 24h-fresh snapshot is acceptable rather than real-time tick data.

## Known failure modes

- Stale data if the 24h regeneration cycle is delayed or fails
- Payment required (402) if the $0.05 USDC fee is not submitted via x402 protocol
- Service unavailable if etherealgoodsco.store is down
- Partial dataset if fewer than 50 coins are available at snapshot time
