## 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 arbipulse-execute-arbitrage-execution-package-68e87039
```

Example prompt: I spotted an arbitrage opportunity between Uniswap and Sushiswap on ETH mainnet for the WETH/USDC pair with 5 ETH — can you pull the full execution package with calldata, gas estimates, and risk assessment so I can decide whether to submit it?

## When to prefer this

Use this endpoint when you have already identified an arbitrage opportunity and need a production-ready execution package — calldata, gas estimates, and risk scores — rather than just a price quote or route suggestion. Ideal for DeFi agents that detect arb signals and need the full transaction payload to submit or evaluate before committing capital.

## Known failure modes

- No profitable arbitrage opportunity found for the given parameters — returns empty or null execution plan
- Stale market data causes an unprofitable plan to appear profitable — profit estimates may be inaccurate by execution time
- Invalid token pair or unsupported chain returns a 400 error
- Gas estimation fails due to RPC issues — partial plan returned without gas figures
- Payment of $0.75 USDC not settled via x402 — returns 402 Payment Required
- Opportunity has already closed (latency between discovery and execution call) — plan returned but marked as expired

## How this service works

Agent-ready execution package — calldata, gas estimates and a risk assessment for any arbitrage opportunity. Built for autonomous trading agents.

## Output

A complete execution package containing: ABI-encoded calldata ready for on-chain submission, estimated gas costs in native token and USD, risk scoring (e.g. slippage risk, sandwich risk, revert probability), expected net profit after gas, and routing details for the arbitrage path.
