Citation-backed flight compensation claim letter across 7 regimes (EU261/UK261/Canada APPR/Brazil ANAC 400/Turkey SHY/India DGCA/Israel ASL) plus Montreal Convention baggage compla

Citation-backed flight compensation claim letter across 7 regimes (EU261/UK261/Canada APPR/Brazil ANAC 400/Turkey SHY/India DGCA/Israel ASL) plus Montreal Convention baggage complaints: deterministic eligibility and amount plus a ready-to-send demand letter that pre-empts the carrier defenses, with escalation path and deadlines. Cheaper eligibility-only check: /api/rights/check ($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.
