# Ethereum Address Profile: ETH/USDC Balances + ENS + OFAC Check on Base

> Ethereum Address Profile: ETH/USDC Balances + ENS + OFAC Check on Base is a paid API for AI agents from api.api-agent-ia.ch, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-25).

Returns ETH balance, USDC balance on Base, primary ENS name on Ethereum mainnet, and OFAC SDN sanctions status for a given wallet address in a single call.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ethereum-address-profile-eth-usdc-balances-ens-ofac-check-on-base-327c9b73
```

Example prompt: Can you pull a full profile for wallet address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — I want its ETH and USDC balances on Base, its ENS name if it has one, and whether it shows up on the OFAC sanctions list?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
