Token Risk Check

by Agent Utility Suite in Onchain & crypto

x402 APIPassing, checked 3 h ago

Is this token safe to buy or accept? For an ERC-20 on Base or Ethereum: owner powers from its code (mint, blacklist, fees, pause, trading switch, limits), upgradeable proxy, renounced ownership, DEX liquidity (Uniswap v2/v3, Aerodrome vs WETH/USDC with USD estimate) and OFAC screening of token and owner. Verdict, score, reasons. $0.01 USDC per call.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.01.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
