# Webacy Smart Contract Risk Score API

> Webacy Smart Contract Risk Score API is a paid API for AI agents from api.webacy.com, paid per call via x402, $0.5/call, status unknown (last checked 2026-10-31).

Performs risk analysis on a smart contract address, including verified-source status, static analysis, asset-type resolution, and optional deployer risk flagging.

## 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 webacy-smart-contract-risk-score-api-b31a4046
```

Example prompt: Can you run a Webacy risk check on this Ethereum contract 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on the eth chain and also check if the deployer looks risky?

## When to prefer this

Use this endpoint when you need on-chain smart contract risk intelligence before interacting with, approving, or investing in a contract. It is the right choice when you need verified-source checks and static analysis combined in one call, and supports an optional deployer risk flag. Prefer this over generic block explorer lookups when you want a structured, scored risk assessment rather than raw contract metadata.

## Known failure modes

- Contract address not found on the specified chain — returns 404 or empty result
- Chain identifier not recognized or unsupported — returns validation error
- Unverified contract with fromBytecode=false may return incomplete analysis
- Deployer risk analysis unavailable if deployer address cannot be resolved
- Payment not attached or insufficient — returns 402 Payment Required
- Rate limiting or API key errors — returns 429 or 401

## How this service works

Risk analysis for a smart contract: verified-source status, static analysis, asset-type resolution, and (optionally) deployer risk.

## Output

Returns a structured risk report for the smart contract including: whether the source code is verified, static analysis findings (e.g. reentrancy, ownership issues), the resolved asset type (ERC-20, NFT, etc.), an overall risk score, and optionally a flag indicating whether the deployer address poses risk.
