Deterministic $0.25 readiness check for /api/grant/loi ($2.00): scores completeness of your funder/project/org/amount/duration inputs against the six-part LOI structure the full product commits to, flags exactly which sections will need [BRACKETED] placeholders, and guesses funder-type register from the name alone. No live funder research, no letter text, no LLM call — pure input grading before you spend $2 on the real draft.
