How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

Output

Returns an AI-powered MEV risk assessment for the proposed swap, including likelihood of sandwich attacks, front-running exposure, slippage safety evaluation, and actionable recommendations to protect the transaction (e.g. tighter slippage, private mempool usage).

Example use cases

Pre-trade MEV risk check

“I'm about to swap 10,000 USDC for ETH on Uniswap on Ethereum with 1% slippage — can you analyze whether this trade is at high risk of being sandwiched or front-run by MEV bots?”

Slippage safety validation

“Is 0.5% slippage tolerance safe for swapping 500 USDC to WBTC on Sushiswap on Ethereum, or am I leaving myself open to MEV attacks?”

DeFi bot protection on Arbitrum

“I want to swap 2000 USDC for ARB on Uniswap on the Arbitrum chain — run an MEV shield check and tell me if I need to tighten my slippage or use a private transaction to avoid bots.”

When to prefer

Choose this endpoint when an AI agent or DeFi user needs pre-trade MEV risk intelligence before executing a swap on a DEX. It is ideal for large swaps where sandwich attack risk is material, when slippage tolerance is uncertain, or when trading illiquid pairs. Prefer over generic gas estimators or slippage calculators when MEV bot exposure is the primary concern.

Side effects

Unsupported DEX name returns an error or low-confidence result
Unsupported chain name causes a validation error
Missing required fields (tokenIn, tokenOut, amount) result in a 400 bad request
Payment failure via x402 (insufficient USDC balance) blocks the request
Extremely small or zero amounts may produce unreliable risk scores
