True when amount_out is an ESTIMATE rather than the exact-out amount asked for. A BUY is an ExactOut order, and many thin tokens have no ExactOut route, so Gateway falls back to quoting the sell leg and then quoting that input forward — which pays the pool fee and crosses the spread twice. Measured at a near-constant ~2.5% across eleven pools spanning $17 to $1,963 of liquidity, and it is reached for ONLY on the thin, high-fee pools where it hurts most. The caller is not overcharged; the order is silently resized, which is what matters to a strategy that asked for a specific quantity. Set extra_params={'approximateIfNoExactOut': false} to require an exact route.
