Classifies an Ethereum-compatible wallet address into one or more behaviour classes (e.g. bot, DeFi trader, human retail) based on on-chain activity patterns including swap share, interval regularity, hour-of-day spread, counterparty count, and contract code.
- [HALOWERK kettenwerk Transaction Simulator](https://www.zero.xyz/c/halowerk-kettenwerk-transaction-simulator-379af678/llms.txt): $0.012/call via x402.
