Shows the status, the settlement asset and amount, the winning method once paid, the frozen fiat materializations (`fiat_methods`), the live progress of every crypto deposit address (amount due vs received) and the `conversion_status` of the auto-conversion. No credentials; rate limited per IP. ## OpenAPI ````yaml /openapi.yaml get /pay/{token}/state openapi: 3.1.0 info: title: CBPay API version: '2.62' description: | CBPay is a multi-currency payment platform: fiat payouts and collections across Latin America, internal transfers, on-chain funding and withdrawals, and KYC screening. Every account holds four independent virtual balances — USDT (the operating currency), USDC, BTC and GOLD (grams of fine gold) — convertible on demand with swaps. Payouts and service fees can be paid from any of the four balances (`PUT /v1/settlement` or per-payout `settlement_asset`), and payins can auto-convert to the asset of your choice (`default_payin_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.
