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 containing: a grade enum (BASED, MID, COOKED, or RADIOACTIVE), a short one-liner summary (max 60 chars), an AI-written roast (max 220 chars), a grade_rule string explaining the grading logic applied, and a facts object containing code_bytes, name, symbol, decimals, total_supply, owner address, owner_renounced flag, proxy_slot, proxy_implementation, proxy_slots_checked, and erc20_shaped flag. Also includes chain, cached, and service metadata fields.
Example use cases
Vet a new token before interacting
“I just heard about this Base token at 0x4200000000000000000000000000000000000006 — can you give me the token verdict on it, especially whether it's a proxy and if the owner is still active?”
Check if a token contract is upgradeable
“Is the token at 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913 on Base an upgradeable proxy? Run a token verdict and tell me what grade it gets and what the proxy slots show.”
Get a fun roast of a meme token
“Roast this Base token contract for me: 0xd9aaec86b65d86f6a7b5b1b0c42ffa531710b6ca — give me the full verdict with its grade and the AI-written roast.”
Technical details
Endpoint
GEThttps://ari001.tailb4ac3a.ts.net/v1/ventures/token_verdict_api/token_verdict_base?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, opinionated structural verdict on a Base ERC-20 token contract — specifically to detect proxy upgradeability and live ownership without relying on holder counts, liquidity, or price data. It is not a safety or scam detector but is ideal for quickly flagging contracts that are proxies with live owners (COOKED) or that don't conform to ERC-20 shape (RADIOACTIVE). Prefer this over generic RPC calls when you want a human-readable grade and roast alongside structured on-chain facts in a single call.
Side effects
- Address is not a contract (returns RADIOACTIVE grade, is_contract: false)
- Address is a contract but not ERC-20 shaped — missing decimals or totalSupply (returns RADIOACTIVE)
- Invalid address format — must match ^0x[a-fA-F0-9]{40}$ (returns 400 or error)
- RPC or network error reading Base chain state (ok: false with error message)
- Payment failure via x402 protocol ($0.018 USDC required per call)
