https://base-facts.yankii.fr/v1/sellcheck

Base honeypot and tax check for trading agents: simulates a small buy and an immediate sell of the token on its deepest WETH pool (Uniswap v2/v3, Aerodrome) inside eth_call, and returns buy tax, sell tax, round-trip loss and whether the sell reverted. $0.005. Simulation at one block, not a guarantee.
