  title: Backrow Flashcards API
  version: v1
  description: 'Programmatic access to Backrow — transcription, notes and AI transformations, flashcards with SM-2 scheduling, knowledge-state, the AI tutor, and engine tools. Available on every plan. Authenticate with a bk_live API key created at https://backrow.ai/platform. Rate limit: 60 requests/minute per key. Send an `Idempotency-Key` header on writes (POST/PATCH/DELETE) to make retries safe — a repeat with the same key replays the original response without re-charging credits.'
