How this service works
Need a quick profile of an address? Returns ETH and USDC balances on Base, its primary ENS name on Ethereum mainnet (or null), and an OFAC sanctions check, in one call; informational only, not legal advice, and returns 503 if the sanctions data is older than 96 h ($0.01 per call).
Output
A JSON object containing the queried wallet address, the network (Base), ETH balance as a string, USDC balance as a string, the primary ENS name (or null if none), and an OFAC object with the sanctions list name, list date, a boolean indicating whether the address is sanctioned, any matches found, and the timestamp of the last downloaded sanctions data. Returns 503 if the sanctions data is older than 96 hours.
Example use cases
Pre-payment wallet compliance check
“Before we send funds, can you check 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B against the OFAC SDN sanctions list and also grab its current ETH and USDC balances on Base?”
DeFi counterparty due diligence
“I need a quick profile on the wallet 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE — give me its ENS name, how much ETH and USDC it holds on Base, and confirm it's not sanctioned.”
User wallet onboarding verification
“A new user just gave me their address 0x71C7656EC7ab88b098defB751B7401B5f6d8976F — can you look up their ENS name, check their Base balances, and verify they're not on the OFAC list before I let them in?”
Technical details
Endpoint
GEThttps://api.api-agent-ia.ch/profil-adresse?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined, single-call snapshot of an Ethereum wallet — covering Base network token balances (ETH + USDC), ENS identity resolution, and OFAC SDN sanctions screening — rather than making separate calls to individual balance, ENS, or compliance APIs. Ideal for pre-payment compliance checks, DeFi counterparty vetting, or onboarding flows where you want to quickly assess both the financial profile and sanctions risk of a wallet address.
Side effects
- 503 Service Unavailable if the OFAC sanctions data is older than 96 hours
- Invalid or malformed Ethereum address returns an error
- Missing required 'adresse' query parameter causes a request failure
- Network issues or Base RPC unavailability may delay or fail balance lookups
- ENS resolution returns null if no primary ENS name is set for the address
