When you are executing transactions, often times you will want to fetch a quote first, to understand what the estimated cost of a transaction will be, and what the estimated final output of the transaction will be. Borderless has a series of streamlined API endpoints to help you.
If you’re just getting started, please check out our quick start guide.

​
Fetching quote details

The quotes endpoints returns estimated or indicative exchange rates between stablecoins and local fiat currencies, as well as the estimated fees and spread that are applied throughout.
These quotes are generally expected to be estimates, not guaranteed. It is likely that the final output will be slightly different than the quote as rates change continuously. Borderless is not responsible for any divergence between quotes and the final executed amount. Borderless passes along the fees of our partner financial institutions (PFIs) at cost.
Fees are calculated in stablecoin currency for withdrawals and fiat currency for deposits, but in future versions will be calculated in USD only.

​
Transaction Limits

Withdrawal and Deposit transactions may be subject to limits, which define the minimum and maximum allowed fiat amounts per transaction. These limits vary depending on: Country, Currency, Payment method, and Asset. The limits object contains:
​
minAmount
string
required
The minimum allowed fiat amount
​
maxAmount
string
required
The maximum allowed fiat amount
​
fiat
string
required
The fiat currency the limites apply to
If either minAmount or maxAmount is null, it means there is no limit set for that value.
Quotes could be calculated based on fromAmount or toAmount. Only one of fromAmount or toAmount could be present at the same time. Quote by toAmount is available for US and EU countries only. If paymentMethod is not provided, the quote will be calculated for the first available option by fiat, country and asset. E.g. if both ACH and Wire option is available for USD to USDC deposit in US any of them could be used and order is not guaranteed.
