Output

Returns a JSON object with the token's name, symbol, decimals, total supply, contract address, chain, owner address and whether ownership is renounced, proxy type and admin if applicable, risky function flags (mint, pause, blacklist, setFee, transferOwnership), bytecode size, scan sources, and a timestamp. Also includes a note explaining that risky functions are identified by 4-byte selector matching in bytecode.

Example use cases

DeFi token safety pre-check

“Before I buy this token, can you scan the contract at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Ethereum and tell me if the owner can mint new tokens, pause transfers, or blacklist wallets?”

Upgradeable proxy detection

“Is the token contract 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 on Polygon an upgradeable proxy, and if so who is the admin?”

Token metadata lookup

“What's the name, symbol, decimals, and total supply of the token at contract address 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 on Arbitrum?”

Technical details

Endpoint

GEThttps://api.sitecheck-api.workers.dev/api/evm/token?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to quickly assess the risk profile of an ERC-20 token contract on EVM chains (Base, Ethereum, Arbitrum, Optimism, Polygon) — especially to detect owner-controlled risks like minting, pausing, or blacklisting before making a trade or investment. Prefer this over manual blockchain explorers when you need programmatic, structured output. It is distinct from Solana token checks, which are handled by a separate endpoint.

Side effects

Invalid or non-existent contract address returns an error or empty result
Unsupported chain identifier causes a 400 or validation error
Non-contract address (EOA wallet) returns hasCode: false with no risky function data
Rate limiting or payment failure returns a 402 Payment Required response
Network or RPC issues for the target chain may cause timeouts
