Fixed gas units (100k simple, 250k complex, 180k liquidity) are typical assumptions, not transaction-specific estimates or quotes. Valid values: standard, high-mev (3x priority fee), low-gas (half); invalid values return HTTP 400 without charge. No transaction simulation, mempool observation, or MEV/sandwich-risk measurement. Use to budget gas for a Base transaction.
