## How to call it through Zero

```sh
zero fetch --capability axon-smart-contract-audit-d9504d3f
```

Example prompt: Can you run an AI security audit on this smart contract — 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 — and tell me if there are any vulnerabilities or red flags I should know about before interacting with it?

## When to prefer this

Use this endpoint when you need a quick AI-generated security assessment of a specific smart contract address, especially before interacting with an unknown DeFi protocol, token, or NFT contract. Prefer this over manual code review when speed matters and the contract address is known. Best suited for EVM-compatible contracts on Base or Ethereum where the bytecode or source is accessible.

## Known failure modes

- Invalid or malformed contract address returns an error response
- Contract address not found on-chain or unsupported chain returns empty or error
- x402 micropayment not completed or insufficient USDC results in 402 Payment Required
- Rate limiting or server overload may return 429 or 503
- AI model failure may return incomplete or null auditReport

## 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 a detailed auditReport string covering identified vulnerabilities, risk levels, and security recommendations generated by AI analysis of the contract.
