## How to call it through Zero

```sh
zero fetch --capability webacy-risk-score-api-0a17d2bb
```

Example prompt: Can you run a Webacy risk score on the Ethereum wallet 0xAbc123...def456 and tell me if it's flagged for any risk issues or suspicious behavior?

## When to prefer this

Choose this endpoint when you need a multi-dimensional, provider-aggregated risk analysis for a blockchain wallet — including contract classification, token standard detection, and specific risk issue identification — rather than a simple balance or transaction lookup. It is especially useful for compliance screening, pre-transaction counterparty risk assessment, and DeFi safety checks across multiple chains (Ethereum, BSC, Polygon, Arbitrum, Optimism, Base, Solana).

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Unsupported chain identifier causes a 400 or invalid chain error
- Address with no on-chain history may return minimal risk data
- Rate limiting or quota exhaustion returns a 429 error
- Missing required 'chain' query parameter causes a 400 bad request
- $0.50 USDC x402 payment failure blocks the request

## How this service works

Comprehensive risk analysis for a blockchain wallet address: contract/EOA classification, token standard, and identified risk issues across all providers.

## Output

Returns a JSON object containing: contract vs EOA classification, token standard (e.g. ERC-20, ERC-721), a risk score, and a list of identified risk issues or flags (e.g. mixer exposure, sanctions, scam associations) across the requested analysis modules.
