Deterministic, letter-scoped preview of /api/deals/subscription-letter ($2.00): runs the same rule engine and reports whether a demand letter is supportable, its type (refund_demand | gift_letter | obstruction_letter), and the computed refund/exposure numbers. No letter text, no LLM. For full duties-in-force + violations + actions/defenses detail see /api/deals/subscription-rights ($0.05).

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.
