## 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 exchange-spot-ticker-f8772430
```

Example prompt: What's the current live spot price of BTC-USD on Coinbase and Kraken right now, including bid, ask, and the price gap between the two exchanges?

## When to prefer this

Prefer this endpoint when you need real-time executable spot prices from both Coinbase and Kraken simultaneously, especially for arbitrage detection or pre-trade price checks. It is more useful than a generic multi-token price endpoint when you need bid/ask spread, 24h OHLCV detail, and cross-exchange price comparison in a single call.

## Known failure modes

- Unsupported or malformed trading pair returns an error (e.g., typos or pairs not listed on both exchanges)
- Network or upstream exchange API outage results in partial or failed response
- Rate limiting from underlying exchange APIs may cause transient failures
- Pairs only available on one exchange may return incomplete data for the other
