How this service works
AI-written token verdict on one Base token contract (query: token, 0x + 40 hex): grade BASED/MID/COOKED/RADIOACTIVE… 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 containing: a grade enum (BASED, MID, COOKED, or RADIOACTIVE) with the rule that produced it, a one-liner description (up to 60 chars), a roast (up to 220 chars), whether the verdict was written by a model or template, and a facts object covering code size, name, symbol, decimals, total supply, owner address, owner_renounced flag, proxy slot values checked (EIP-1967, beacon, ZeppelinOS), and whether the contract is ERC-20-shaped.
Example use cases
Quick rug check before buying
“Before I ape into this token, can you get me the verdict on 0x532f27101965dd16442E59d40670FaF5ebb142E4 on Base? I want to know if it's BASED, MID, COOKED, or RADIOACTIVE and why.”
Verify token ownership renounced
“Can you check whether the owner is renounced on this Base token contract 0x4200000000000000000000000000000000000006? I want the full verdict including proxy slots and the grade rule.”
Audit token before listing
“We're considering listing 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb on Base — run the token verdict on it and tell me the grade, any proxy weirdness, and the roast.”
Technical details
Endpoint
GEThttps://ari001.tailb4ac3a.ts.net/v1/ventures/base_token_verdict_api/base_token_verdict?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, opinionated on-chain grade for a specific Base network token contract address — especially when you want to quickly surface proxy upgrade slots and live owner risk without paying for a full audit service. It does NOT check holders, liquidity, or price, so prefer it for structural/contract-state checks rather than market safety assessments. Best for agents screening tokens before deeper analysis or surfacing red flags in a conversational DeFi assistant.
Side effects
- Address is not a deployed contract on Base → grade RADIOACTIVE, is_contract: false
- Address is a contract but not ERC-20 shaped (no decimals/totalSupply) → grade RADIOACTIVE
- Invalid or malformed token address (not 0x + 40 hex) → request rejected by schema validation
- RPC read failure or network timeout → ok: false with error message
- Token exists but has unusual state → grade based on proxy/owner rules, may return template-written verdict
