Every account holds four independent virtual balances — USDT (the operating currency), USDC, BTC and GOLD (grams of fine gold) — that never mix or convert automatically. Payouts and service fees can be paid from any of the four balances: set a default with `PUT /v1/settlement` or override per payout with `settlement_asset`. All amounts are decimal strings in each currency's precision (6 decimals for USDT/USDC/GOLD, 8 for BTC). Errors always return `{"error": "", "message": ""}`. servers: - url: https://api.qbank.cl/platform description: Live (production, real money) - url: https://cryptobank.qbank.cl/platform description: Test (sandbox, simulated money — pk_test_ keys) security: - bearerAuth: [] tags: - name: Receipts description: >- Branded PDF receipt per operation, with a public signed-QR authenticity check, receipt_url on every response/webhook and automatic email delivery on final states. - name: Authentication description: Register and log in account members.
