# Universal checkout page (public)

> Public branded HTML page behind the `checkout_url` returned by `POST /v1/payins` with `method: "checkout"`. The payer opens it without credentials, picks a country and fiat method, a crypto option (deposit address with scannable QR) or pays directly from the CBPay app (merchant QR + alias always visible), and the page updates itself when the payment is confirmed. The token is cryptographically derived; an invalid one answers 404. Rate limited per IP.

  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": "<code>", "message": "<detail>"}`.
