Call before buying, swapping into or accepting any Base ERC-20, to learn if you can sell it back. $0.02, ~1-3 s, measured on-chain: honeypot test (simulated buy then sell via the deepest pool: sell ok? round-trip loss vs fees), per-pool transfer tax from real recent swap receipts, USD liquidity per pool (Uniswap v2/v3, Aerodrome, Slipstream), sell quotes, and an ok/caution/avoid verdict citing each fact. Errors: 400/503 JSON {error}, not charged.
