How this service works
Paid on-chain token, wallet, contract and research data over x402 on Base.
Output
Returns a JSON object with a 'query' field set to 'mev-analyze' and an 'opportunities' array listing any detected MEV patterns, arbitrage vectors, or sandwich attack signals found in the analyzed transaction. An empty array indicates no MEV opportunities were detected.
Example use cases
Frontrunning risk check on swap
“I'm about to submit a large DEX swap — can you analyze this pending transaction for MEV exposure before I send it? Hash is 0xabc...def, to 0xUniswapRouter, value 1.5 ETH, gas price 30 gwei.”
Sandwich attack detection on DeFi tx
“Check this DeFi transaction for sandwich attack patterns — it went to 0xDefiPool, hash 0x999...111, input 0xswapExactETHForTokens, value 0.5 ETH, gas price 15 gwei.”
Post-trade MEV audit for arbitrage
“After this trade settled, I want to know if any MEV bots extracted value from it — transaction hash 0xfeed...cafe, to 0xSushiRouter, value 0.8 ETH, gas price 25 gwei, input 0x.”
Technical details
Endpoint
POSThttps://coinop.publicvm.com/api/v1/mev/analyze?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically detect MEV exposure, frontrunning risk, or arbitrage opportunities within a specific on-chain transaction, especially on Base or EVM-compatible chains. Prefer it over generic blockchain explorers when you need structured MEV-specific intelligence rather than raw transaction data.
Side effects
- Missing or malformed tx object returns an error or empty opportunities array
- Invalid transaction hash format may result in analysis failure
- Network timeouts if the blockchain node is unreachable
- Payment failure via x402 if USDC balance is insufficient (HTTP 402)
- Transactions with missing fields (e.g. no gasPrice) may yield incomplete analysis
