## 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 intel-hugen-tokyo-smart-contract-audit-lite-eb00a232
```

Example prompt: Can you run a quick contract audit on 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum and give me the risk score and any security flags — I want the structured lite report, not the full AI narrative.

## When to prefer this

Choose this endpoint when you need fast, cheap, machine-readable smart contract risk signals at $0.02 per call — ideal for automated pipelines, pre-transaction screening, or bulk contract vetting where structured flags matter more than AI narrative. Use the $0.50 /intel/contract-report endpoint instead when you need a full AI-synthesized risk assessment with explanatory prose.

## Known failure modes

- Unverified or undeployed contract address returns no source analysis, only partial flags
- Unsupported blockchain network returns an error or empty result
- Invalid or malformed contract address causes a 400-level error
- Contract with no on-chain activity may lack ownership or transaction-based signals
- Payment failure (USDC not received on Base or Solana) blocks the response

## How this service works

Smart contract audit summary — verified source analysis, security flags, proxy detection, risk scoring 0-100. No AI verdict prose — structured flags only. For AI-synthesized risk assessment, see /intel/contract-report ($0.50). Accepts USDC payments on Base and Solana

## Output

Returns a structured JSON object containing: a numeric risk score from 0–100, categorized security flags (e.g. reentrancy, centralization), proxy/upgradeable pattern detection, contract ownership details, and verified source code status. No AI-generated prose or narrative verdict — machine-readable flags only.
