Exam-suite sampler / preview — deterministic, no LLM. For the exam (and optional topic) you name, returns exactly what each paid exam product (prep, mock, grade, flashcards, explain) requires and produces for those inputs, plus real external study-resource links. Agent-tier preview under the exam suite’s $0.50–$1 price points.

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.
