If the date you request falls outside the Kemenag table, the MABIMS API doesn't guess. It recomputes the month length from the Neo MABIMS criteria. This post tears down the engine behind the mabims-computed source.

One of my favorite endpoints on mabims.dev isn't /today or /convert, but /hilal/viz. This endpoint generates a 720×1280 PNG showing a complete evening sky visualization with moon position, MABIMS criteria pass/fail status, and a sky chart with stars. A deep dive behind the scenes.
