How this service works
One-call verdict on any ERC20 on Base, Ethereum, Polygon, Arbitrum or Optimism: a machine-readable label for who can act on your balance (no-owner-powers, owner-can-intervene, owner-controls-balances, not-a-token), a headline, a plain-language reading and a paste-ready card - with the deterministic evidence underneath, selector by selector. Label, score and card come from the deployed bytecode and live state, never from a model. Research, not investment advice.
Output
Returns a structured verdict containing: a machine-readable label (no-owner-powers, owner-can-intervene, owner-controls-balances, or not-a-token), a headline summary, a plain-language explanation of the risk profile, a paste-ready card for sharing, and deterministic per-selector evidence derived from deployed bytecode and live on-chain state.
Example use cases
DeFi due diligence before investing
“Before I buy into this token, can you check the contract 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum and tell me whether the owner has any powers over balances or if it's truly decentralized?”
Flagging risky tokens in a wallet
“I see an unknown ERC20 at 0x95aD61b0a150d79219dCF64E1E6Cc01f0B64C4cE on Ethereum in my wallet — can you pull a verdict on it and tell me if it's a real token and if anyone can freeze my funds?”
Auditing a Base token before listing
“We're about to list a new token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base — can you give me the machine-readable risk label and the full bytecode evidence so I can include it in our listing review?”
Technical details
Endpoint
GEThttps://flat-rate-llm.kikoribera03.workers.dev/v1/evm/verdict?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, bytecode-grounded risk verdict on an ERC20 token without relying on third-party token lists or AI inference. It is ideal for DeFi due diligence, wallet risk flagging, exchange listing review, or any agent workflow that needs a machine-readable label plus auditable evidence for token contracts on Base, Ethereum, Polygon, Arbitrum, or Optimism.
Side effects
- Invalid contract address format — returns error if the address is not a valid EVM hex address
- Address is not a token — label returned is 'not-a-token' if the contract does not implement ERC20
- Unsupported chain — error if chain parameter is not one of: base, ethereum, polygon, arbitrum, optimism
- Contract not deployed — error if address has no bytecode at the given chain
- Payment not provided — x402 payment required, returns 402 if USDC payment is missing
