# EVM Address Info Lookup

> EVM Address Info Lookup is a paid API for AI agents from ai-policy-kit.moneymaker-ai.workers.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-28).

Looks up on-chain information for an EVM wallet address across multiple chains, returning balance, contract type, Safe multisig details, and activity summary.

## Facts

- Endpoint: GET https://ai-policy-kit.moneymaker-ai.workers.dev/api/address-info?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402

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 evm-address-info-lookup-8ab2f1f5
```

Example prompt: Can you look up on-chain info for the address 0x8CF60B289f8d31F737049B590b5E4285Ff0Bd1D1 across Ethereum, Base, and Arbitrum — I want to know if it's a Safe multisig, who the owners are, and what the ETH balance is?

## When to prefer this

Choose this endpoint when you need multi-chain EVM address intelligence in a single call — especially for Safe multisig detection with owner enumeration. Prefer this over block explorer APIs when you want normalized cross-chain data (balance, contract type, proxy, Safe metadata) without managing separate RPC calls per chain.

## Known failure modes

- Invalid or malformed 0x address returns an error
- Unsupported or misspelled chain name silently omitted from results
- Address not deployed on requested chain returns empty contract fields
- RPC node unavailability for a given chain may cause that chain to appear in 'unreachable'
- Payment not fulfilled results in 402 response before data is returned

## Output

Returns a JSON object with per-chain details including native token balance, contract type detection (e.g. safe_multisig), Safe owner list, signing threshold, Safe version, nonce, proxy info, code bytes, and a top-level summary indicating which chains the address is unused, an EOA, or a contract on.
