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.

price-ascending: candidates are ordered by the listed price of the operation, with no managed-first preference applied. Unlike /v1/apis, this surface does not rank Apiosk-settled listings above federated ones — a comparison that reorders on commercial grounds is not a comparison. Pass sort=managed_first for the catalog's ordering.

Compared: listed price, settlement rail and input compatibility. Not measured yet: latency, reliability, result quality, and provider terms such as rate limits, jurisdiction and licensing.
