How this service works
Smart contract security scan for AI agents: give a chain id and contract address, get Slither static-analysis findings (reentrancy, unchecked calls, arbitrary sends, etc.), proxy/upgradeability status and the list of owner/role-gated admin functions (mint, pause, blacklist, upgrade). Works on any Sourcify-verified contract on Ethereum, Base, Arbitrum, Optimism, Polygon, BNB. Use before approving, depositing into or trading a token/protocol. Unverified contracts are rejected without charge.
Output
Returns a JSON object with vulnerability findings from Slither static analysis (e.g. reentrancy, unchecked calls, arbitrary sends), proxy and upgradeability status, and a list of privileged/admin-gated functions (mint, pause, blacklist, upgrade). Unverified contracts are rejected without charge. Returns ok:true on success with a monitor ID and first check status.
Example use cases
Pre-approval token contract audit
“I'm about to approve a new ERC-20 token at 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum mainnet (chain ID 1) — can you scan it for reentrancy issues, unchecked calls, and tell me if the owner can mint or pause the contract?”
DeFi protocol deposit safety check
“Before I deposit into this Arbitrum yield protocol at 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 (chain ID 42161), run a Slither security scan and let me know if it's a proxy contract or has any upgrade admin functions I should worry about.”
New Base token rug-pull risk assessment
“There's a new token on Base (chain ID 8453) at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — scan it for security vulnerabilities and tell me if the deployer has blacklist or arbitrary send capabilities before I trade it.”

Endpoint
GEThttps://contractlens-api.appin60.com/monitor?utm_source=zero.xyzWhen to prefer
Use ContractLens when you need a fast, automated static-analysis security verdict on a specific smart contract before interacting with it — especially for approving token spends, depositing into DeFi protocols, or evaluating a new token. It is ideal when the contract is Sourcify-verified on one of the six supported chains and you need Slither findings plus admin function enumeration in a single call. Prefer this over manual audits or generic block explorers when an AI agent needs a structured, machine-readable risk assessment at transaction time.
Side effects
- Contract not Sourcify-verified — rejected without charge
- Unsupported chain ID — only Ethereum, Base, Arbitrum, Optimism, Polygon, BNB are supported
- Invalid contract address format — returns error
- Payment not completed — x402 payment of $0.99 USDC required before results are returned
- Contract has no source code — treated as unverified and rejected
- Network timeout reaching the target chain RPC
