## How to call it through Zero

```sh
zero fetch --capability axon-smart-contract-audit-f47daa97
```

Example prompt: Can you audit the smart contract at 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 and tell me if it has any security vulnerabilities or red flags I should know about?

## When to prefer this

Use this endpoint when you need a quick, on-demand AI-powered security assessment of a specific smart contract address without requiring a full manual code review. It is particularly valuable when evaluating unknown DeFi protocols, new token launches, or any contract before committing funds or integrating it into a product. Prefer this over manual audits when speed and cost matter most ($1 USDC per call via x402).

## Known failure modes

- Invalid or malformed contract address returns an error response
- Contract address not found on-chain may yield no meaningful audit data
- Micropayment failure (x402) on Base network blocks the request
- Unverified or non-existent contract may return limited audit information
- Rate limiting or service downtime on the Vercel deployment

## How this service works

Axon provides AI-powered crypto intelligence endpoints covering token research, market analysis, contract auditing, sentiment tracking, news summarization, portfolio advice, deep research, text translation, language detection, SEO content generation, and contract explanation. All analytical endpoints require x402 micropayment on Base.

## Output

A JSON object containing the queried contract address and an AI-generated audit report detailing security findings, identified vulnerabilities, risk levels, and any detected malicious or suspicious patterns in the smart contract code.
