## 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 crucible-wallet-activity-audit-fab082b4 -d '<json body>'
```

Example prompt: Can you audit the Ethereum wallet 0x3fC91A3afd70395Cd496C647d5a6CC9D4B2b7FAD for risky or suspicious transactions over the last 60 days and give me a risk score?

## When to prefer this

Use this endpoint when you need a cited, evidence-backed risk audit of a specific Ethereum mainnet wallet's transaction history — especially when you need flagged individual transactions rather than just an aggregate risk score. Prefer it over generic blockchain explorers when you need structured findings with confidence scores and source citations suitable for agent decision-making or compliance reporting.

## Known failure modes

- Invalid or non-checksummed wallet address returns a validation error
- No on-chain activity found in the specified window returns empty findings array
- Network timeout or upstream RPC failure may return a service error
- Very large windowDays values may increase latency or hit data limits
- Non-Ethereum-mainnet addresses (e.g. L2, Solana) are not supported

## How this service works

Pay-per-call Web3 agent services: wallet, token and agent security audits; token prices, depeg checks and portfolio valuation; cited fact-checking and source research.

## Output

Returns a structured object containing: a numeric risk score (0–1), a confidence score, a list of findings (each with a reason and the flagged transaction hash), the number of transactions analyzed, the lookback window used, cited source URLs with hashes, evidence claims tied to sources, and a content hash for verification.
