Sanctions screening against the 6 official lists (UN, EU, OFAC, UK, FR, CH)

Matches with 0-100 confidence score and level (forte/possible/faible), matched alias, source list, regime, birth year, plus the inventory of loaded lists — each with its entry count, publication date and `precision_publication` saying whether that date is the upstream official publication or Sirenic's ingestion date (OFAC publishes none). Never a bare yes/no. Carries the common `provenance[]` envelope (states and reading rules: GET /v1/lecture, free). Preserve coverage and provenance. Missing data is not zero; a name match is not proof of identity.

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.
