## 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 2s-io-cex-24h-spot-ticker-11951bcb
```

Example prompt: What's the current price, best bid/ask, and 24-hour percent change for BTC-USD on the centralized exchange right now?

## When to prefer this

Prefer this endpoint when you need real CEX spot market data (not aggregated/averaged prices) for a specific trading pair — particularly when bid/ask spread, OHLC, or volume from a centralized exchange matters. Distinct from CoinGecko aggregate endpoints which blend multiple sources; use this for exchange-native price discovery.

## Known failure modes

- Invalid or unsupported pair symbol returns an error or empty result
- Pair format must be dash-separated (e.g. BTC-USD, not BTCUSD) or the endpoint may reject it
- Downstream exchange data unavailable may cause stale or missing fields
- Payment failure (x402) if USDC balance is insufficient returns 402 error

## How this service works

Centralized-exchange 24h ticker for a spot pair (e.g. BTC-USD), free/keyless: current price, best bid/ask, 24h open/high/low, 24h + 30d volume, and 24h percent change. Real CEX spot quote — distinct from crypto.token-price (CoinGecko aggregate).

## Output

Returns a JSON object containing the current spot price, best bid, best ask, 24h open/high/low, 24h percent change, 24h volume, and 30-day volume for the requested trading pair from a centralized exchange.
