How this service works
Label a known EVM address from a curated, committed dataset: major stablecoin + token contracts (USDC on every chain we settle on, USDT, DAI, WETH, WBTC), DEX routers (Uniswap, 1inch, 0x), canonical L1↔L2 bridges, large exchange hot/cold wallets, and burn/system addresses. Deterministic and offline - the provenance field states the dataset revision. Unknown addresses return {found:false}, not an error.
Output
A structured label for the queried EVM address, identifying it as a known entity such as a stablecoin contract (e.g. USDC on a specific chain), DEX router (Uniswap, 1inch, 0x), canonical L1/L2 bridge contract, or exchange hot/cold wallet. Returns null or unknown for unrecognized addresses.
Example use cases
Example prompt
“What is this Ethereum address? Can you label 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 for me — is it a known contract, exchange wallet, or bridge?”
Technical details
Endpoint
POSThttps://agent402.tools/api/address-labelWhen to prefer
Use this endpoint when you need a quick, reliable label for a well-known EVM address from a curated, committed dataset — especially for major stablecoins (USDC, USDT, DAI), WETH, WBTC, popular DEX routers, L1↔L2 bridges, or large exchange wallets. Prefer this over on-chain lookups or Etherscan scraping when you need a fast, paid-but-deterministic answer for commonly encountered addresses in DeFi workflows.
Side effects
- Address not found in curated dataset — returns unknown/null label
- Malformed address (not 0x-prefixed or wrong length) — validation error
- Payment failure via x402 protocol — 402 response
- Network timeout — retry recommended
