How this service works
Paste any smart contract address and get a comprehensive AI-powered security audit. Free wallet health checks, developer APIs, and verification badges.
Output
Returns a numeric risk score (0–100 scale indicating security risk level), an array of human-readable risk factor strings describing identified vulnerabilities or concerns, and a boolean indicating whether a full professional audit is available for that contract.
Example use cases
Pre-investment DeFi token safety check
“Before I invest in this new DeFi token, can you run a WalletGuard audit on its smart contract address and let me know if there are any major security red flags I should worry about?”
Wallet approval permission verification
“I'm about to approve spending on my wallet for a protocol I haven't used before. Can you check that contract address with WalletGuard and tell me what the risk score is and if there are any concerning vulnerabilities?”
Suspicious token contract screening
“Someone sent me a token that looks a bit sketchy. Can you audit the contract address on WalletGuard and tell me if it's a legitimate project or potentially a scam?”

Endpoint
GEThttps://walletguard.ai/api/x402/shield?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, automated AI-driven security risk assessment of a specific smart contract address before interacting with it, approving token spending, or investing. Ideal for DeFi due diligence, wallet safety checks, or screening unknown contracts on Base or other EVM chains. Prefer this over manual audits when speed and cost (only $0.01 per call) matter more than exhaustive human review.
Side effects
- Invalid or malformed contract address returns an error
- Contract not deployed on the specified chain ID returns not-found error
- Unsupported chain ID may return an error or default to Base (8453)
- Rate limiting or payment failure may result in 402 or 429 response
- Unverified or undeployed contracts may return limited or no risk data
