# Base Address Risk Snapshot

> Base Address Risk Snapshot is a paid API for AI agents from x402-research-iota.vercel.app, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-29).

Returns a public-data red-flag snapshot for a Base (chain 8453) address, including contract type, proxy status, source verification, age, activity, ETH/USDC balances, and a risk level rating.

## Facts

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 base-address-risk-snapshot-57fd9f61
```

Example prompt: Before I interact with 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base, can you pull a risk snapshot — tell me if it's a contract or wallet, whether it's verified, if it's an upgradeable proxy, how old it is, and what the overall risk level is?

## When to prefer this

Use this endpoint when an agent needs a fast, pre-interaction due-diligence check on an unfamiliar Base (chain 8453) address — especially before approving token transfers, interacting with a DeFi protocol, or sending funds. It is purpose-built for Base and returns a uniquely structured risk snapshot combining on-chain metadata (proxy type, verification, EIP-7702 status, age, balances) into a single call. Prefer over generic block explorer lookups when you need a machine-readable risk level and structured flags rather than raw chain data.

## Known failure modes

- 400 Bad Request — invalid or malformed address parameter (e.g. missing 0x prefix, wrong length)
- Missing ?address= query parameter returns error
- Address not found on Base chain may return unknown risk level or limited data
- Network or provider outage may delay or fail response
- Non-Base chain addresses will not return meaningful results (Base/chain 8453 only)

## How this service works

Use before interacting with an unfamiliar Base (chain 8453) address: returns a public-data red-flag snapshot (contract vs EOA, EIP-7702 delegation, source verification, upgradeable proxy, age, activity, ETH/USDC balance, risk level). Pass ?address=0x... Errors: 400 invalid address. Informational only.

## Output

A JSON object containing: the address, chainId (8453), accountType (contract/eoa/eoa_eip7702_delegated), risk level (low/medium/high/unknown), whether source code is verified, proxy details (standard, upgradeable, admin, implementation), whether it is EIP-7702 delegated, address age in days, firstSeenAt timestamp, sentTxCount, ETH and USDC balances, and an array of risk flags each with a code, severity level, and detail string.
