API Documentation


This section describes methods for creating invoices and obtaining information about invoices.
The functionality of the accounts allows you to accept payment in the specified equivalent, and the coin and network are chosen by the payer
For example, you can create an invoice for payment of 100 USD, the payer will be asked to select coin and network in which it will be more convenient for him to pay, for example, in USDT, TRX, BNB and others. The amount due will be recalculated automatically at the exchange rate.
When paying, you can also additionally indicate the percentage to be paid (field insurancePercent), in this case, the payer will be shown the amount to be paid as 100 USD, but the payment amount, for example, in USDT will be equal <AMOUNT TO PAY> * <USDT/USD RATE> + <insurancePercent> Example: you created an invoice for payment of 75 USD and specified insurancePercent equal to 5. When choosing a payment coin, for example, USDT (we will assume that the USDT/USD rate is 1=1), the payer will be asked to pay 78.75 USDT (5% of 75 = 3.75)
You can also specify that the payer pays the network commission by specifying the includeFee: true parameter. In this case, the commission chosen by the payer will be added to the final payment amount.
It is possible to specify the percentage of price slippage (field slippagePercent). If it is indicated, then if the payer, when paying, sends an amount more or less than the payment amount by the specified percentage, then the account will be considered closed. Example: the payer needs to pay 100 USDT, you specified a slippage percentage of 0.5%. In this case, if the payer sends the amount of 99.99 USDT (from 99.5 to 100.5), the invoice will be considered completed
