How this service works
AI-written token verdict on one token contract on Base: grade (BASED/MID/COOKED/RADIOACTIVE), a one-liner and a… Returns: an AI-written token verdict on one token contract: grade (BASED/MID/COOKED/RADIOACTIVE, a stated rule over the contract's own state), a one-liner and a roast, and the facts read: code size, name, symbol, decimals, supply, owner(), proxy slots. It does not read holders, liquidity or price and makes no safety or legitimacy call. Query: token (token contract, 0x + 40 hex).
Output
Returns a JSON object with: a grade enum (BASED=clean, MID=one risk flag, COOKED=both proxy and live owner, RADIOACTIVE=not a contract or not ERC-20 shaped), a one-liner summary (≤60 chars), a roast string (≤220 chars), the grade rule applied, whether written by model or template, and a facts object containing code_bytes, name, symbol, decimals, total_supply, owner, owner_renounced, proxy_slot, proxy_implementation, proxy_slots_checked, is_contract, and erc20_shaped flags.
Example use cases
Screening a new Base memecoin
“Can you check the contract 0x532f27101965dd16442e59d40670faf5ebb142e4 on Base and tell me if it's BASED or COOKED — I want to know if it's a proxy, whether the owner is renounced, and get the one-liner verdict.”
Due diligence before trading a Base token
“Before I ape into this Base token at 0x4ed4e862860bed51a9570b96d89af5e1b0efefed, can you pull its contract grade and tell me if there's a live owner or any proxy slots set?”
Automated token contract audit in a DeFi agent
“Run a contract verdict check on 0x50c5725949a6f0c72e6c4a641f24049a917db0cb on Base — I need the grade, facts like decimals and total supply, and the roast so I can decide whether to list it.”
Technical details
Endpoint
GEThttps://ari001.tailb4ac3a.ts.net/v1/ventures/ethereum_contract_abi_service/token_verdict_base?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, on-chain-only structural verdict on a Base ERC-20 contract — specifically to detect proxy patterns and unrenounced ownership. It does NOT check holders, liquidity, price, or trading history, so it is not a safety or legitimacy oracle. Prefer this over general blockchain explorers when you need a machine-readable grade with a standardized rule and roast for automated agent pipelines or DeFi screening workflows.
Side effects
- Address is not a deployed contract → grade RADIOACTIVE, is_contract false
- Address is a contract but lacks decimals/totalSupply (not ERC-20 shaped) → grade RADIOACTIVE
- Invalid address format (not 0x + 40 hex) → input validation error
- RPC node unavailable → service error with ok:false and error field
- Address is a valid ERC-20 but RPC timeout on owner() call → partial facts returned
