How this service works
Real-Time Smart Contract Security & Bytecode Audit Oracle for Base Mainnet, payable via x402.
Output
Returns a JSON object with the contract address, a boolean indicating if it's a contract, a boolean indicating if it's a proxy, the proxy's implementation address (if applicable), a risk level string (e.g. low/medium/high), an integer risk score, bytecode size in bytes, and an array of security findings detailing any vulnerabilities or anomalies detected.
Example use cases
DeFi protocol safety check before depositing
“Before I deposit funds into this Base protocol, can you audit the contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and tell me if it's safe — what's the risk score and are there any security issues?”
Proxy contract implementation discovery
“I found this contract address on Base — 0x2626664c2603336E57B271c5C0b26F421741e481 — can you check if it's a proxy and what implementation address it points to?”
Pre-investment token contract audit
“I'm considering investing in a token on Base. Can you run a security audit on the contract 0x940181a94A35A4569E4529A3CDfB74e38FD98631 and give me the risk level and any bytecode findings?”
Technical details
Endpoint
GEThttps://baseaudit-x402.vercel.app/v1/proxyWhen to prefer
Choose this endpoint when you need automated, real-time security assessment of a specific smart contract on Base Mainnet before interacting with it programmatically. It is purpose-built for Base (not Ethereum mainnet or other L2s) and returns structured risk metadata ideal for agent decision-making. Prefer this over manual block explorer review when you need machine-readable risk scores and proxy detection in a single call.
Side effects
- Invalid address format (not a 42-character hex string) returns validation error
- Address is an EOA (externally owned account) rather than a contract — is_contract may be false with no audit findings
- Contract not deployed on Base Mainnet returns empty or error response
- Network congestion or RPC failures may cause timeout or incomplete audit
- Payment failure via x402 protocol prevents request from being processed
