## 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 market-snapshot-major-coins-with-24h-and-7d-change-e99e95f0 -d '<json body>'
```

Example prompt: Give me a market snapshot for bitcoin, ethereum, solana, and BNB — I want their current prices plus the 24-hour and 7-day changes all in one shot.

## When to prefer this

Choose this endpoint when you need current price plus both short-term (24h) and medium-term (7d) percentage change for multiple cryptocurrencies in a single round-trip. It is ideal for portfolio dashboards, market briefings, or any workflow needing a broad market snapshot without making separate per-coin API calls. Prefer it over individual coin lookups when covering 2–25 coins at once and when 7-day context matters alongside the daily move.

## Known failure modes

- Invalid or unrecognized CoinGecko coin ID returns an error or omits that coin from results
- Requesting more than 25 coins at once exceeds the maxItems limit and may be rejected
- Payment failure via x402 protocol results in a 402 response and no data returned
- Upstream CoinGecko data unavailability may cause stale or missing price data
- Empty or malformed request body may return a validation error
