How this service works
AI-written token verdict on one token contract: grade (BASED/MID/COOKED/RADIOACTIVE, a stated rule over the… 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: ok (boolean), a result object containing the token address, grade (BASED/MID/COOKED/RADIOACTIVE), grade_rule (human-readable explanation of why the grade was assigned), one_liner (≤60 char summary), roast (≤220 char AI-written quip), written_by (model or template), and facts (is_contract, code_bytes, name, symbol, decimals, total_supply, owner, owner_renounced, proxy_slot, proxy_implementation, proxy_slots_checked, erc20_shaped). Also includes chain, cached flag, and service name. Does NOT include holder counts, liquidity, or price data.
Example use cases
Due diligence on a new Base token
“Before I ape into this token, can you pull the Xerxes verdict on 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA — I want the grade, whether the owner is renounced, and if there are any proxy slots active?”
Roast a meme coin contract
“Roast this Base meme coin contract for me — run a Xerxes token verdict on 0x532f27101965dd16442E59d40670FaF5eBB142E4 and tell me what grade it gets and what the AI one-liner says.”
Verify ERC-20 shape before integration
“I need to integrate a token at 0xB6fe221Fe9EeF5aBa221c348bA20A1Bf5e73624c into our system — can you check the Xerxes verdict to confirm it's ERC-20 shaped with valid decimals and total supply, and not RADIOACTIVE?”
Technical details
Endpoint
GEThttps://ari001.tailb4ac3a.ts.net/v1/ventures/token_verdict_api/token_verdict?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, opinionated on-chain structural assessment of a Base token contract — specifically checking ERC-20 conformance, proxy upgrade slots, and owner renouncement — without needing price, holder, or liquidity data. Ideal for pre-integration checks, due diligence automation, or entertaining AI roasts of sus contracts. Not suitable when you need live market data, holder distribution, or a formal security audit.
Side effects
- Address is not a deployed contract → grade RADIOACTIVE, is_contract: false
- Address is a contract but lacks decimals/totalSupply → grade RADIOACTIVE, erc20_shaped: false
- Malformed token address (not 0x + 40 hex) → input validation error, ok: false
- Contract is unreachable or RPC error → ok: false with error field populated
- Rate limit or payment failure → 402 Payment Required
