## 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-evm-address-identity-lookup-be24c3d7 -d '<json body>'
```

Example prompt: Before I send funds, can you look up the identity of the Ethereum address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 — I want to know if it's a known entity like an exchange or protocol, whether it's a contract, if there are any scam flags, and what its ENS name is?

## When to prefer this

Choose this endpoint when you need a comprehensive identity and reputation profile for an EVM address before interacting with it — especially when you want labels (exchange, protocol, scam), ENS resolution, contract verification, and activity stats in a single call across Ethereum, Base, Arbitrum, Optimism, Polygon, or zkSync. Prefer this over raw on-chain RPC calls when you want pre-aggregated reputation signals and human-readable labels without building custom indexing logic.

## Known failure modes

- Invalid or malformed EVM address returns an error
- Address not found on the specified network returns nulls for most fields
- Unsupported network value returns a validation error
- No ENS or labels available returns null for those fields
- Rate limiting or payment failure (x402) returns a payment-required error

## 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 containing: ENS name (if any), network, canonical address, public labels (e.g. exchange, bridge, fund), data source, scam/reputation alerts, verification status, whether it is a contract, native token balance, transaction count, token transfer count, proxy info, and implementation addresses.
