GET /v1/base/token-tax

unprobed

Token tax check and transfer restriction scan for any ERC-20 on Base (GET ?contract=0x… or POST body {contract}). Returns buy tax, sell tax, transfer limits, cooldown rules, blacklist/whitelist functions and a trade-safety verdict. Call before any agent swaps, quotes or routes a token, to avoid tokens that eat most of the trade in fees. $0.02 USDC

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
