How this service works
Get all available labels for an ETH or Base 0x address. Labels may describe owner identity, smart contract name, wallet behavior patterns and other properties. Also resolves ENS and Base names if available.
Output
A set of labels for the queried address, potentially including owner identity (e.g. known person or organization), smart contract name if applicable, wallet behavior pattern tags, and resolved ENS or Base name if one exists.
Example use cases
Identify unknown wallet before transacting
“I just received a payment from 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE and I want to know who or what this address is before I interact with it — can you pull up all its labels, check if it's a known entity or smart contract, and see if it has an ENS name?”
Classify smart contract or EOA address
“Can you check this address 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D for me and tell me whether it's a smart contract or a regular wallet, what it's called if it is a contract, and what behavioral tags are associated with it?”
Research Base address identity and reputation
“I'm looking into a Base address 0x4200000000000000000000000000000000000006 — can you find out everything known about it, including who owns it, any Base name it resolves to, and what kind of activity patterns it's been flagged with?”
Technical details
Endpoint
POSThttps://mesh.heurist.xyz/x402/agents/ChainbaseAddressLabelAgent/get_address_labelsWhen to prefer
Use this endpoint when you need rich, multi-dimensional labels for an Ethereum or Base address including identity, contract metadata, behavioral tags, and ENS/Base name resolution in a single call. Prefer this over raw ENS resolvers when you need more than just a name — especially for behavioral classification or smart contract identification.
Side effects
- Address not found or unlabeled — returns empty label set
- Invalid 0x address format — returns validation error
- Address is on an unsupported chain — no labels returned
- Network timeout or upstream Chainbase API failure
- Rate limiting or payment failure due to x402 micropayment issue
