# Vextorium Wallet Identity

> Vextorium Wallet Identity is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-10-13).

Returns identity metadata for an EVM wallet address: public labels, ENS name, contract status, scam flags, EIP-7702 delegation, balance, and activity counts.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 vextorium-wallet-identity-ac7db96d -d '<json body>'
```

Example prompt: Who is 0x28C6c06298d514Db089934071355E5743bf21d60 on Ethereum — is it a known exchange, a contract, flagged as a scam, and what's its current ETH balance?

## When to prefer this

Use this endpoint when you need a quick, pre-interaction identity snapshot of any EVM address — especially to screen counterparties before sending funds, identify whether an address belongs to a known protocol or exchange, check for scam flags, or resolve ENS names. Prefer this over raw blockchain RPCs when you need aggregated identity signals (labels, alerts, contract metadata) in a single call without building your own indexer.

## Known failure modes

- Invalid or malformed EVM address returns an error
- Unsupported network enum value causes a validation error
- Address with no on-chain history may return nulls for most fields
- Rate limiting or payment failure (x402) blocks the request
- Network congestion may cause slow or stale data responses

## How this service works

Who an EVM address is before you interact: public labels (exchange, protocol, bridge, fund...), ENS name, whether it is a contract and which, verification, scam flag or poor reputation, EIP-7702 delegation, balance and activity.

## Output

A JSON object with the address's ENS name, human-readable label(s) (e.g. 'Binance', 'Uniswap'), whether it is a smart contract, whether the contract is verified, any scam/reputation alerts, EIP-7702 proxy and delegation info, native token balance, total transaction count, and total token transfer count. Data is sourced from Blockscout.
