Late-claim interest check — insurers owe STATUTORY INTEREST when they pay late, and most policyholders never collect it. Deterministic day-count math: TX 18%/yr + fees (weather claims prime+5 w/ 542A notice), FL property from the NOTICE date (CFO quarterly table), NY no-fault 2%/month, AZ 10%, GA health 12%, CA health 15% + auto-include penalty. ERISA self-funded gate, clean-claim assumptions stated, limitations gates. Honest-no where the interest belongs to the provider. 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.
