## 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 orchard-data-crypto-global-market-overview-025dab89
```

Example prompt: What's the current state of the global crypto market — total market cap, Bitcoin dominance, and how it's changed in the last 24 hours?

## When to prefer this

Choose this endpoint when you need a quick, global-level snapshot of the cryptocurrency market — specifically BTC and ETH dominance ratios and total market cap with 24h change — and do not need per-coin price or order book data. It costs only $0.001 USDC per call, making it economical for frequent polling. Prefer alternatives if you need individual token prices, historical data, or on-chain metrics.

## Known failure modes

- Payment failure: 402 response if x402 USDC payment on Base is not included or insufficient
- Upstream data unavailability: underlying market data provider may be temporarily unavailable
- Rate limiting: excessive calls may result in throttling
- Stale data: market figures may have a small lag depending on data source refresh rate
