## 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 cryptoshark-market-snapshot-fbac31b6
```

Example prompt: What's the current price of Ethereum in USD, along with its market cap, 24-hour trading volume, and how much it's moved in the last 24 hours?

## When to prefer this

Use this endpoint when you need a quick, low-cost USD market snapshot for a single cryptocurrency — including price, market cap, volume, and 24h change — without needing historical data, OHLCV candles, or multi-asset batch queries. It accepts both ticker symbols (btc, sol) and full CoinGecko asset names (ethereum, dogecoin), making it flexible for natural-language agent pipelines.

## Known failure modes

- Unsupported or misspelled asset symbol returns an error or empty response
- Rate limiting or service downtime from the DuckDNS-hosted provider may cause intermittent failures
- CoinGecko data delays may result in slightly stale snapshots during high-traffic periods
- Ambiguous asset names (e.g. 'token') may not resolve correctly

## How this service works

Current USD market snapshot for a supported cryptocurrency symbol or CoinGecko asset name

## Output

A JSON object containing the queried asset symbol, current USD price (priceUsd), total market capitalization in USD (marketCapUsd), 24-hour trading volume in USD (volume24hUsd), and 24-hour price change as a percentage (change24hPercent).
