Formatting Parameters

We have a few URL parameters to help format the API response data. URL parameters are appended to the URL where the first parameter is preceded with "?" and subsequent parameters are preceded with "&". Here is an example:

https://api.sendwyre.com/v3/rates?pretty&as=priced

You can see ?pretty is the first parameter, and &as= is the second with a value of priced. If you remove the URL parameters the formatting reverts to a less structured state.

Pagination Parameters

We split our tabular data into pages of 25 items. You can apply the parameters below to any request for tabular to adjust the pagination.

Rates Formatting

When fetching current rates there are also additional formatting parameters available.

GET https://api.sendwyre.com/v2/rates

The ordering of the trade pair in the key represents the direction of an exchange. For example, BTCUSD is the rate used for BTC into USD conversions (e.g. the sell rate). On the other hand, converting USD into BTC (the buy rate) would use the opposite rate under USDBTC.

You can also view the rates in different formats according to your preference:

Examples

https://api.sendwyre.com/v2/rates?as=divisor - source amount / rate = destination amount (default)

https://api.sendwyre.com/v2/rates?as=multiplier - source amount * rate = destination amount

https://api.sendwyre.com/v2/rates?as=priced&pretty&format=json_numberstring - shows both divisor and multiplier values

https://api.sendwyre.com/v2/rates?as=priced&pretty&format=csv - downloads rates as CSV file
For example, if 1 BTC is selling at 9000 USD, USDBTC will be 9000 in the divisor view and (1/9000) in the multiplier view.

Currency Decimal Place Rounding

For our suite of fiat and cryptocurrencies, it is good to be aware of how Wyre goes about rounding each currency so you or your end users can always input the correct number of digits past the decimal place. The full list of how we round currencies can be found below.

Another thing to take note of is how we round if we are given an input that goes beyond the number of decimal places that we allow. If we round X currency to 8 digits past the decimal place and the user inputs 9 digits, we will always round down to make sure users are not hit with insufficient funds. For example, if a user inputs 0.123456789, this will be rounded down to 0.12345678 to make sure the order can go through.
