# Base Token Verdict

> Base Token Verdict is a paid API for AI agents from ari001.tailb4ac3a.ts.net, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-12).

Returns an AI-written verdict (grade, one-liner, roast, and on-chain facts) for a token contract on Base, reading code size, name, symbol, decimals, supply, owner, and proxy slots.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability base-token-verdict-6c837ca2
```

Example prompt: Give me the AI verdict on this Base token contract — 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed — I want the grade (BASED, MID, COOKED, or RADIOACTIVE), the roast, and any on-chain facts like supply, owner, and whether it's a proxy.

## When to prefer this

Use this endpoint when you need a fast, opinionated AI-written summary of a Base token contract's on-chain properties — especially for quick pre-trade due diligence on token contract metadata. Prefer this over raw RPC calls when you want a graded verdict plus a roast and plain-language summary rather than raw hex. Do not use this if you need holder distribution, liquidity depth, price data, or transfer history — this endpoint only reads contract-level state.

## Known failure modes

- Invalid or malformed token address (not 0x + 40 hex) returns an error
- Contract address not deployed on Base returns empty or error response
- Non-ERC-20 contract address may yield partial or unexpected facts
- Network timeout or RPC read failure returns no verdict
- Payment not sent or insufficient USDC results in 402 payment required

## How this service works

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.

## Output

Returns a structured AI-generated verdict including: a grade enum (BASED, MID, COOKED, or RADIOACTIVE), a one-liner description, a roast of the token, and raw on-chain facts: bytecode size, token name, symbol, decimals, total supply, owner() return value, and proxy storage slots. Does not include holder counts, liquidity data, or price information.
