Example prompt: Can you run an AI security audit on the smart contract at 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 and tell me if there are any vulnerabilities or red flags I should know about?

## When to prefer this

Use this endpoint when you need an AI-generated security audit of a specific deployed smart contract before interacting with it, investing, or integrating it into a workflow. Prefer this over generic code review tools when targeting on-chain EVM contracts by address.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address not found on supported chain returns no data
- Network or micropayment failure prevents report generation
- Contract with no on-chain code (EOA) may return empty or error result
- Rate limiting or x402 payment rejection causes 402 response

## 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

Returns a JSON object containing the contract address and a detailed auditReport string summarizing security findings, potential vulnerabilities, risk factors, and overall safety assessment of the smart contract.
