Example use cases
Example prompt
“Can you run a full AI security audit on the smart contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum (chain ID 1)? I want to know if it has any vulnerabilities before I interact with it.”
Technical details
Endpoint
POSThttps://walletguard.ai/api/x402/audit/standard?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive AI-powered security audit of an EVM-compatible smart contract and are willing to pay $29 USDC per audit. Prefer this over free tools when you need a detailed, structured audit report with a verifiable badge, or when auditing unverified contracts by supplying raw Solidity source code. Best for pre-investment due diligence, developer security reviews, or when integrating audit verification into automated workflows.
Side effects
- Invalid or malformed contract address returns a 400 error
- Unsupported chain ID returns a validation error
- Payment failure due to insufficient USDC balance prevents job creation
- Contract not found on-chain and no sourceCode provided causes audit failure
- Rate limiting or service unavailability returns 429 or 503
