Output
Returns a classification of the queried wallet address, describing its type (e.g. EOA, smart contract, multisig) and activity characteristics across the specified EVM chains
Example use cases
DeFi user wallet type check
“I need to know what kind of wallet 0xAbCd1234567890abcdef1234567890abcdef5678 is — is it a regular EOA, a contract, or something else? Check it on Ethereum and Base.”
Anti-bot screening for airdrop
“Before we send out airdrop tokens, can you classify these wallets to see if any of them look like bots or contracts? Start with 0xDEADBEEF1234567890abcdef1234567890abcdef on Arbitrum and Optimism.”
Compliance wallet profiling
“We need to profile the wallet 0x9999888877776666555544443333222211110000 across Ethereum, Base, Arbitrum, and Optimism for our KYC review — what type of wallet is it and how active is it?”
Technical details
Endpoint
POSThttps://kette.netzhandwerker.de/wallet/classifyWhen to prefer
Choose this endpoint when you need to classify or profile a specific EVM wallet address across multiple chains simultaneously (Ethereum, Base, Arbitrum, Optimism) and want a lightweight, pay-per-call approach via x402 micropayments in USDC. Prefer this over general block explorers when you need structured classification data rather than raw transaction history.
Side effects
- Invalid wallet address format (not 0x + 40 hex chars) — likely a 400 error
- Unsupported chain name passed in chains array
- Wallet has no on-chain activity — may return empty or unknown classification
- Payment failure via x402 protocol — endpoint returns 402 if USDC payment not completed
- Too many chains requested (max 4) — request rejected
