## 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 syra-arbitrage-scanner-1c68f229
```

Example prompt: Scan the top 15 CoinMarketCap crypto assets for arbitrage opportunities and show me which ones have the biggest price spreads across USDT exchanges right now.

## When to prefer this

Use this endpoint when you need real-time cross-exchange arbitrage scanning for the top CMC assets ranked by spread. Ideal for automated trading bots or agents looking to identify the most profitable arbitrage windows on USDT-paired markets. Prefer over generic market data endpoints when you specifically need spread-ranked arbitrage signals rather than raw price data.

## Known failure modes

- Payment not completed — returns 402 if USDC payment not received
- limit exceeds max of 25 — validation error
- No arbitrage opportunities found for the scanned assets
- Exchange data unavailable — stale or missing venue data
- Rate limiting if too many requests in short window
