# Ethereum Token Verdict

> Ethereum Token Verdict is a paid API for AI agents from api.arysphere.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Returns an AI-written verdict (grade, one-liner, roast) plus on-chain facts and Uniswap V3 price/depth for an Ethereum ERC-20 token contract address.

## 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 ethereum-token-verdict-f5918963
```

Example prompt: Check this CA for me — run the Ethereum token verdict on 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 and tell me its grade, the one-liner, the roast, and what the on-chain facts show.

## When to prefer this

Choose this endpoint when you need a quick, opinionated on-chain summary of an Ethereum ERC-20 token contract, including a graded verdict, AI-written roast, raw contract facts (supply, owner, proxy), and Uniswap V3 liquidity data — all in a single paid call. Prefer it over raw RPC calls when you want pre-processed, human-readable output rather than raw ABI decoding. Not a substitute for formal token audits or holder/wallet analysis.

## Known failure modes

- Invalid or malformed contract address (must be 0x + 40 hex chars) returns a validation error
- Contract address exists but is not an ERC-20 token — may return missing or null fields
- No Uniswap V3 pool found for the token — price and depth fields will be absent or null
- Payment not settled via x402 — returns 402 Payment Required
- Ethereum mainnet RPC call timeout or node outage — returns a 5xx error
- Token contract has no owner() function — owner field will be absent

## How this service works

Check this CA: Ethereum mainnet ERC-20 verdict of a token contract address. Not financial advice.  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; plus the deepest Uniswap V3 pool's USD price and depth. No holders, no safety or legitimacy call.

## Output

Returns an AI-generated verdict object containing: a grade label (BASED, MID, COOKED, or RADIOACTIVE) with a stated rule tied to the contract's own state, a one-liner description, a roast, and raw on-chain facts (code size, name, symbol, decimals, total supply, owner address, proxy slots). Also includes the deepest Uniswap V3 pool's current USD price and liquidity depth.
