## How to call it through Zero

```sh
zero fetch --capability arbipulse-profit-calculator-102afb9d
```

Example prompt: Can you calculate the net P&L for an arbitrage trade — buying ETH at $3,420 on Binance and selling at $3,438 on Coinbase with a position size of 5 ETH? I want to see the full itemized fee breakdown so I know if it's actually profitable.

## When to prefer this

Use this endpoint when you have identified a potential arbitrage opportunity and need to verify net profitability after all costs before executing. Ideal after using ArbiPulse price-scanning endpoints (DEX, CEX, perps) to confirm whether a detected spread actually yields profit once fees, gas, and slippage are accounted for.

## Known failure modes

- Missing required trade parameters returns an error
- Invalid price or size values cause computation failure
- Unsupported exchange or venue identifiers return an error
- Extreme edge-case inputs (zero size, negative prices) may return validation errors
- Payment failure (x402) blocks access to the endpoint

## How this service works

Itemized fee breakdown and net P&L for any arbitrage trade — fees, slippage and gas. For arbitrage and trading agents.

## Output

An itemized breakdown of all fees (trading fees, gas, slippage, etc.) applied to the trade, plus the net profit or loss after all costs are deducted, enabling the agent to determine whether the arbitrage opportunity is genuinely profitable.
