GET /api/execution/check
unprobed
One verdict on a concrete order before it is sent: effective price, slippage in bps and in USD, how much of the visible book the order eats, and the largest size that still fits your slippage budget. Walks the live order book level by level (you never download the book) and answers ok / ajustado / riesgo with the reasons. Use it to size an order, to compare venues, or before quoting a fill.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
