Credit-card benefit coverage check — extended warranty, purchase protection, trip delay, cell phone, return protection — against ISSUER-verified published benefit guides (Chase, Amex, Capital One, Citi, HSBC, Amex UK, RBC CA + negative facts for Discover/gutted cards). Caps, deductibles, eligibility windows, and the filing deadlines that kill late claims, computed. No LLM.

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.
