NAME

wallet-label — identifies well-known evm addresses: cex hot/cold wallets, dex routers, nft marketplaces, popular mev bots, bridges, and stablecoins

     Content-Type: application/json
     X-PAYMENT:    <signed-transferWithAuthorization>

     { ... }

DESCRIPTION

Identifies well-known EVM addresses: CEX hot/cold wallets, DEX routers, NFT marketplaces, popular MEV bots, bridges, and stablecoins. Best-effort labelling against an in-handler dictionary; Etherscan v2 'getcontractcreation' adds is_contract + deployer for unknown contracts. Returns label, category, and the source of the match. Use it as a wallet label, address tagger, known-address lookup, EOA-vs-contract check, or deployer tracer.

INPUT — request schema

property	type	description	req?
address	string	0x-prefixed 20-byte EVM address.	optional
wallet	string	Alias for address; accepts the same 0x-prefixed EVM address.	optional
chain	string	EVM chain. Default 'ethereum'. 'eth' and 'mainnet' map to ethereum. enum: base · ethereum · eth · mainnet · polygon · arbitrum · optimism	optional

OUTPUT — response shape

field	type	description
address	string	EVM address that was looked up, returned in lowercase hex form.
chain	string	Chain the lookup ran against (e.g. ethereum, base, polygon).
is_contract	string	True if the address has bytecode deployed, false if it's an externally owned account.
deployer	string	Address that deployed the contract, pulled from Etherscan getcontractcreation when available.
creation_tx	string	Transaction hash that created the contract, or null for EOAs and unknown contracts.
label	string	Human-readable name for the address (e.g. 'Binance Hot Wallet 14', 'Uniswap V3 Router').
category	string	Bucket the label falls into: cex, dex, bridge, stablecoin, nft-marketplace, mev-bot, etc.
source	string	Where the match came from: in-handler dictionary, etherscan-creation, or unmatched.

EXAMPLES — two ways to call

EXAMPLE 1 · curl

curl -X POST https://x402.agentutility.ai/wallet-label \
  -H 'Content-Type: application/json' \
  -d '{ }'

first response = 402 Payment Required with payment requirements; sign + retry with X-PAYMENT.

EXAMPLE 2 · mcp

# Install the MCP package for this endpoint's cluster
npx -y @agentutility/mcp-<cluster>

# Required: EVM private key with USDC on Base
export X402_PRIVATE_KEY=0x...

# Then call the wallet-label tool from your MCP-aware agent.

MCP server handles payment automatically — your coding agent just calls the tool by name.
