A member scans a merchant's QR code; we debit their crypto assets, and the upstream pays equivalent fiat to the merchant.

decode quotes payments
Our revenue is the difference between the upstream quote and the user's actual payment.
Four Steps, Each with an Essential Detail
| Stage | Endpoint | Key points |
|---|---|---|
| Decode | POST /v1/qrpay/decode | Unrecognized schemes are rejected immediately, never guessed |
| Quote | POST /v1/qrpay/quotes | One quote per payable asset; the member chooses one |
| Pay | POST /v1/qrpay/payments | Requires a payment authorization ticket |
| Query | GET /v1/qrpay/orders/{id} | Alert on unknown states; do not fall back |
Three Things This Service Does Not Offer
- There is no supplementary charge—funds are released when the member personally selects Pay.
- No refund initiation—the upstream provides no such endpoint. Only the recipient merchant can initiate one. However, refunds do occur, and you must handle them; see Orders and Refunds.
- Members cannot choose the debit currency—it is selected automatically by their payment preferences.
