Pair

GET 
/pair/:from/:to

Returns the minimum and maximum deposit amount and the rate for a pair of coins.

from and to can be coin-network or if network is omitted, it will default to the mainnet. E.g eth-ethereum, eth-mainnet or eth all refer to ETH on the Ethereum network. eth-arbitrum refers to ETH on Arbitrum network.

The rate is determined after incorporating network fees. Without specifying an amount, the system will assume a deposit value of 500 USD. This can be adjusted by adding the amount query parameter.

Rate Example Computations

• BTC price: 30000 USD
• USDT price: 1 USD
• depositCoin: USDT
• depositNetwork: ethereum
• settleCoin: BTC
• USDT receiving fee: 10 USD
• BTC sending fee: 5 USD
• Default deposit amount: 500 USD

/pair/usdt-eth/btc

Without specifying the amount at the endpoint, we can calculate the rate as follows:

Rate X = ( default deposit amount - (USDT receiving fee + BTC sending fee) / default deposit amount) / BTC price
Rate X = 0.000032333333333

/pair/usdt-eth/btc?amount=10000

With a specified amount at the endpoint, such as 10000, we can calculate the rate as follows:

Rate Y = ( specified amount - (USDT receiving fee + BTC sending fee) / specified amount) / BTC price
Rate Y = 0.000033283333333

With a specified amount of 10000, the rate is higher. This is because the 15 USD combined network fee has a reduced impact on larger shifts, making it less significant in the overall cost of the 500 USD shift.
