# ContractLens Token Security Scan

> ContractLens Token Security Scan is a paid API for AI agents from contractlens-api.appin60.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-14).

Runs Slither static analysis and admin-power detection on a Sourcify-verified EVM smart contract, returning a risk verdict, security findings, proxy/upgradeability status, and privileged admin functions.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability contractlens-token-security-scan-c4ffbdea
```

Example prompt: Before I buy any of this token, can you run a security scan on the DEGEN contract at 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed on Base (chain ID 8453) — I want to know the risk level, any Slither findings like reentrancy or unchecked calls, and whether the owner can mint or pause the token.

## When to prefer this

Use this endpoint when you need a structured, agent-ready security assessment of an EVM token or protocol contract before any financial action (approval, deposit, trade). It is especially valuable when you need Slither static-analysis findings (reentrancy, unchecked calls, arbitrary sends) combined with admin-power enumeration (mint, pause, blacklist, upgrade) and ownership info in a single call. Prefer it over manual audits or generic block explorer lookups when you need machine-readable risk verdicts. Works across Ethereum, Base, Arbitrum, Optimism, Polygon, and BNB chain. Only Sourcify-verified contracts are supported.

## Known failure modes

- Unverified contract (not on Sourcify) — rejected without charge
- Invalid or malformed contract address — error response
- Unsupported chain ID — error response
- Contract not deployed at address on specified chain — error response
- Payment not provided or insufficient — 402 response

## 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

A JSON object containing: ok status, chain name, token metadata (name, symbol, decimals), market data (price, volume, liquidity, pair age, buys/sells), a verdict object with risk level (LOW/MEDIUM/HIGH), numeric score, and plain-English summary, an adminPowers map listing privileged functions (mint, pause, blacklist, upgrade), control/owner info (address and multisig type), Slither flags with issue description and severity, proxy/upgradeability status, and Sourcify verification match type.
