Example prompt: Check ArbiPulse right now and tell me which crypto spot pairs have profitable arbitrage opportunities across Binance, Coinbase, Kraken, and Bybit — I want to see the net profit after fees for each opportunity.

## When to prefer this

Use this endpoint when you need real-time, fee-adjusted CEX spot arbitrage signals specifically across Binance, Coinbase, Kraken, and Bybit. Prefer this over DEX arbitrage endpoints when you want centralized exchange opportunities without dealing with gas costs, flash loans, or on-chain execution. Choose this over statistical/pairs arbitrage endpoints when you want pure spot price discrepancies rather than mean-reversion signals.

## Known failure modes

- Exchange API timeout or outage causes stale or missing price data for one or more venues
- No profitable arbitrage opportunities exist at the moment — returns empty or zero-profit results
- Rate limiting from upstream exchange APIs resulting in incomplete data
- Network latency causes price data to be slightly outdated, reducing actual profit vs. reported

## How this service works

## Output

A list of live arbitrage opportunities across the four supported CEXs (Binance, Coinbase, Kraken, Bybit), including the asset/pair, buy exchange, sell exchange, buy price, sell price, spread, and net profit after exchange fees are deducted.
