How this service works
Wallet identity resolution. ENS name, wallet age, tx count, DeFi protocols, token holdings, NFTs, behavioral labels. Ethereum and Base.
Output
Returns a structured identity object containing: resolved ENS name (or null), wallet age in days and first-seen timestamp, transaction counts per chain (Ethereum and Base), DeFi protocols the wallet has interacted with, ERC-20 token holdings count, NFT holdings count, and an array of behavioral labels derived from on-chain activity patterns.
Example use cases
Example prompt
“Can you pull up the full identity profile for wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44e — I want to know their ENS name, how old the wallet is, what DeFi protocols they've used, and any behavioral labels from their on-chain activity?”
Technical details
Endpoint
GEThttps://wallet-intel-api-production-3ec7.up.railway.app/api/v1/identity/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive on-chain identity snapshot for a single Ethereum or Base wallet — combining ENS resolution, wallet age, DeFi protocol history, token/NFT holdings, and behavioral labels in one call. Prefer this over raw blockchain RPC calls when you want pre-aggregated, labeled intelligence rather than raw transaction data.
Side effects
- Invalid or malformed address (not 0x-prefixed or not 42 chars) returns an error
- Wallet address with zero on-chain activity may return mostly null/empty fields
- ENS resolution failure returns null for ENS field
- Rate limiting or upstream data provider unavailability may return 5xx errors
- Address not found on either Ethereum or Base returns empty profile
