How this service works
Frontrun monitoring: sandwich attacks, toxic flow, and MEV activity detection.
Output
Returns raw MEV activity data including detected sandwich attack events, front-running transactions, toxic flow classification, attacker wallet addresses, affected transactions, and associated profit/loss metrics for the queried token or wallet.
Example use cases
Example prompt
“Check if there have been any sandwich attacks or MEV front-running targeting the token 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum — I want to see recent toxic flow and attacker wallets.”
Technical details
Endpoint
POSThttps://emc2ai.io/x402/bitquery/frontrunwatch/rawWhen to prefer
Use this endpoint when you need to detect or investigate sandwich attacks, front-running, or toxic MEV flow around specific tokens, wallets, or transactions on DEXes. Prefer this over generic blockchain explorers when you specifically need structured MEV classification and attacker identification rather than raw transaction data.
Side effects
- Invalid token or wallet address returns empty result set
- Unsupported chain returns error or no data
- Payment failure (insufficient USDC) blocks the request with 402
- Rate limiting if called too frequently
- Missing required parameters returns 400 bad request
- No MEV activity in the queried timeframe returns empty array
