## 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 aitoollab-crypto-market-data-api-fdea4984
```

Example prompt: Can you pull the latest crypto market snapshot — I want to see the top coins with their current prices and 24-hour changes, plus the overall BTC dominance and total market cap?

## When to prefer this

Use this endpoint when you need a quick, cost-effective snapshot of top cryptocurrency prices, BTC dominance, and aggregate market cap in a single call. Prefer this over heavier market data APIs when you only need summary-level data rather than deep order books, historical OHLCV, or individual token analytics.

## Known failure modes

- API returns 402 Payment Required if USDC payment header is missing or insufficient
- Network timeout if upstream market data provider is slow
- Empty or stale data if market data feed is unavailable
- Malformed response if query parameters are invalid
