# ChainVerdict Wallet Dossier

> ChainVerdict Wallet Dossier is a paid API for AI agents from chainverdict.xyz, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-13).

Returns a behavioral profile of a Base address — EOA or contract type, first/last seen timestamps, transaction and counterparty counts, contract verification status, and any raised flags.

## 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 chainverdict-wallet-dossier-9738f925
```

Example prompt: Before I send anything to 0x4e59b44847b379578588920cA78FbF26c0B4956C on Base, can you pull a full dossier on that address — whether it's an EOA or contract, when it was first and last active, how many transactions and unique counterparties it has, and whether the contract is verified or any flags have been raised?

## When to prefer this

Use this endpoint when you need a comprehensive behavioral overview of a single Base address before transacting — especially when you need multiple signals (type, age, activity volume, counterparties, flags) in one call rather than querying individual endpoints separately. Prefer this over the OFAC screen alone when you want broader due diligence beyond sanctions checking, or over a balance check when you need historical activity context rather than current holdings.

## Known failure modes

- Address not found or never active on Base — may return empty profile or 404
- Invalid address format — returns validation error
- Address has no on-chain history — counts and timestamps may be null or zero
- RPC/chain read latency causing timeout
- Payment not processed (x402 flow failure) — request not fulfilled

## How this service works

Wallet risk profile for a Base address before you pay it or accept payment from it: EOA or contract, first and last seen, transaction and counterparty counts, contract-verification status, and any flags raised. Behavioural signals only — they describe activity, not intent.

## Output

Returns a structured behavioral profile of the Base address including: whether it is an EOA or contract, first-seen and last-seen timestamps, total transaction count, unique counterparty count, contract verification status (for contracts), and any behavioral flags detected. Signals are descriptive of activity patterns, not predictive of intent.
