## How to call it through Zero

```sh
zero fetch --capability axon-smart-contract-audit-0b3b31e1
```

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

## When to prefer this

Choose this endpoint when you need a quick AI-powered security assessment of a specific smart contract address, especially for DeFi, token, or NFT contracts, and you want structured findings without waiting for a full manual audit. It is well-suited for pre-investment or pre-interaction screening workflows where an on-demand micropayment model ($1 USDC via x402) is acceptable.

## Known failure modes

- Invalid or malformed contract address returns an error response
- Contract not deployed on supported chain returns empty or error audit
- Micropayment via x402 not fulfilled results in 402 Payment Required response
- Rate limiting or server errors on the Vercel deployment may cause timeouts
- Contract with no verifiable source code may produce limited or inconclusive audit results

## How this service works

All analytical endpoints require x402 micropayment on Base.

## Output

A JSON object containing the contract address and a detailed AI-generated audit report describing security vulnerabilities, suspicious patterns, access control issues, potential exploits, and an overall risk assessment for the given smart contract.
