Serving billions of calls to 1,000,000+ developers and end users worldwide

Why 10,000+ developers love Abstract's APIs

Easy to implement and maintain

We built Abstract because most of the API's we've used in the past simply weren't great. Our APIs are built the way we think API's should be: with excellent documentation, multiple easy to use libraries, and tutorials to get you started.

Speed and scale built into everything we do

Something like IP geolocation is probably part of a critical business processes and flow, so we built it (as all of our APIs) for use at scale and at blazing speeds. These aren't just marketing phrases, but fundamental features of our APIs.

Reliable uptime and great support

Developers trust Abstract because of our reliable uptime and excellent technical support that will help get you live quickly, keep you running smoothly, and resolve any issues you have fast regardless of where you are or what you're building.

The Exchange Rate and Currency Conversion API makes it easy to get and manipulate the latest currency data

The Exchange Rate and Currency Conversion API Documentation

REST

The Exchange Rate and Currency Conversion API, like all of Abstract's APIs, is organized around REST. It is designed to use predictable, resource-oriented URL's and to use HTTP status codes to indicate errors.

HTTPS

The Exchange Rate API requires all communications to be secured TLS 1.2 or greater.

API Versions

All of Abstract's API are versioned. The Gender API is currently on Version 1.

Your API Key

Your API key is your unique authentication key to be used to access Abstract's Exchange Rate API. Note that each of Abstract's API has a unique API key, so you will need different keys to access the Exchange Rate and IP Geolocation APIs, for example. To authenticate your requests, you will need to append your API key to the base URL.

Overview of Endpoints for Exchange Rate and Currency Conversion

Abstract's Exchange Rate and Currency Conversion API contains two main endpoints for accessing currency and exchange rate data:

  • /latest/ returns the latest exchange rate(s), either for a specific currency pair or for all currencies in our database
  • /convert/ converts one currency into the equivalent amount of another currency or currencies, at the latest exchange rate, a historical exchange rate, or over a historical time series.

Latest Exchange Rate Endpoint (/latest/)

The /latest/ endpoint returns the most recent exchange rate for a base currency. If no target currency or currencies are specified, then all currencies in our database are returned. You can see a full list of supported currencies at the bottom of this documentation.

https://currency.abstractapi.com/v1/latest
    ? api_key = YOUR_UNIQUE_API_KEY
    & base = USD

This was a successful request, and because no target currency or currencies were included, the exchange rate of all available currencies were included in the response:

{
    "base": "USD",
    "last_updated_unix": "1593614038",
    "last_updated_utc""Wed, 01 Jul 2020 14:33:58 +0000",
    "exchange_rate": {
        "EUR": 0.889758,
        "CAD": 1.35676,
        "AUD": 1.44753,
        "GBP": 0.807175,
        "CHF": 0.946451,
        "CNY": 7.06409,
        ...
        ...
    }
}

/latest/ Exchange Rate Endpoint - API Request Parameters

PARAMETER

TYPE

DETAILS

api_key required

String

Your unique API key. Note that each user has unique API keys for each of Abstract's APIs, so your Exchange Rate API key will not work for as your IP Geolocation API key, for example.

base required

String

The base currency used to get the latest exchange rate(s) for. Uses the ISO 4217 currency standard (e.g., USD for United States Dollars), like all currency parameters in this API. You can see a full list of supported currencies here.

target

String

The target currency or currencies to get the exchange rate of versus the base currency. Like the base parameters, any currency passed here follows the ISO 4217 standard. If multiple currencies are passed in the target, they should be separated by commas (e.g., &target=EUR,CAD,AUD)

/latest/ Exchange Rate Endpoint - API Responses

The API response is returned in a universal and lightweight JSON format.

PARAMETER

TYPE

DETAILS

base

String

The base currency used to get the exchange rates.

last_updated_unix

String

The Unix timestamp of when the returned data was last updated.

last_updated_utc

String

The UTC timestamp of when the returned data was last updated.

exchange_rate

Object

A JSON Object containing each of the target currency as the key and its exchange rate versus the base currency as that key's value.

Example: Specifying Target Currencies for the /latest/ Endpoint

Rather than returning the latest exchange rate for all currencies, you can specify one or more particular currencies you'd like the latest exchange rate for. Below is a sample request to get the latest exchange rates specifying the United States Dollar (USD) as the base currency and the Singapore Dollar (SGD), Malaysian Ringgit (MYR), and Indonesian Rupiah (INR) as the target currencies.

https://currency.abstractapi.com/v1/latest
    ? api_key = YOUR_UNIQUE_API_KEY
    & base = USD
    & target = SGD,MYR,IDR

The request was valid and successful, and so it returns the following:

{
    "base": "USD",
    "last_updated_unix": "1593614038",
    "last_updated_utc""Wed, 01 Jul 2020 14:33:58 +0000",
    "exchange_rate": {
        "SGD": 1.39392,
        "MYR": 4.28634,
        "IDR": 14312.03
    }
}

Metering and Billing for the /latest/ Endpoint

Each request to the /latest/ endpoint counts as a single use of the API, regardless of how many target currencies are specified or not.

Currency Conversion Endpoint (/convert/)

The /convert/ endpoint is the most powerful and flexible endpoint in Abstract's Exchange Rate and Currency Conversion API. At its core, it converts one currency (the base currency) into an equivalent amount of another currency (the target currency). Its power comes from the ability to set specific amounts to convert, as well as historical dates and even time series to get the exchange rate of.

Below is a very simple example of the /convert/ endpoint in which a specific amount of United States Dollars (USD) ($150) is converted to Euros.

https://currency.abstractapi.com/v1/convert
    ? api_key = YOUR_UNIQUE_API_KEY
    & base = USD
    & target = EUR
    & base_amount = 150

This was a successful request, and the converted because no target currency or currencies were included, the exchange rate of all available currencies were included in the response:

{
    "base": "USD",
    "target": "EUR",
    "base_amount": 150,
    "converted_amount": 133.19,
    "exchange_rate": 0.887417,
    "last_updated_unix": "1593614038",
    "last_updated_utc""Wed, 01 Jul 2020 14:33:58 +0000",
}

/convert/ Exchange Rate Endpoint - API Request Parameters

PARAMETER

TYPE

DETAILS

api_key required

String

Your unique API key. Note that each user has unique API keys for each of Abstract's APIs, so your Exchange Rate API key will not work for as your IP Geolocation API key, for example.

base required

String

The base currency used to get the latest exchange rate(s) for. Uses the ISO 4217 currency standard (e.g., USD for United States Dollars), like all currency parameters in this API. You can see a full list of supported currencies here.

target required

String

The target currency to get the exchange rate of versus the base currency. Like the base parameters, any currency passed here follows the ISO 4217 standard.

base_amount

Float

The amount of the base currency to convert into the target currency. If this parameter is not passed, it will default to 1.

date

String

The date to use in getting the base to target exchange rate. Must be in the format of YYYY-MM-DD. If this is parameter is not passed, it will default to the current day and get the latest available rate.

/convert/ Exchange Rate Endpoint - API Responses

The API response is returned in a universal and lightweight JSON format.

PARAMETER

TYPE

DETAILS

base

Float

The base currency used to get the exchange rates.

target

Float

The target currency used to get the exchange rates.

base_amount

Float

If a base_amount to convert is passed as a request parameter, it is returned here.

converted_amount

Float

The base_amount of the base currency converted into the target currency.

exchange_rate

Float

The exchange rate used to convert the base currency into the target currency.

date

String

If a date is passed as a request parameter, it is returned here.

last_updated_unix

String

The Unix timestamp of when the returned data was last updated.

last_updated_utc

Object

The UTC timestamp of when the returned data was last updated.

Example: Not specifying a base_amount in the /convert/ endpoint

If you do not specify a base_amount in the request, the API will default to 1, which effectively returns the exchange rate from the base to the target currencies.

https://currency.abstractapi.com/v1/convert
    ? api_key = YOUR_UNIQUE_API_KEY
    & base = USD
    & target = SGD

The request was valid and successful, and so it returns the following:

{
    "base": "USD",
    "target": "SGD",
    "base_amount": 1,
    "converted_amount": 1.39367,
    "exchange_rate": 1.39367,
    "last_updated_unix": "1593614038",
    "last_updated_utc""Wed, 01 Jul 2020 14:33:58 +0000",
}

Example: Specifying a historical date in the /convert/ endpoint

If you specify a date in the request, the API will return the historical rate for that particular day.

https://currency.abstractapi.com/v1/convert
    ? api_key = YOUR_UNIQUE_API_KEY
    & base = USD
    & target = SGD
    & date = 2020-01-01

The request was valid and successful, and so it returns the following:

{
    "base": "USD",
    "target": "SGD",
    "target": "2020-01-01",
    "base_amount": 1,
    "converted_amount": 1.34827,
    "exchange_rate": 1.34827,
    "last_updated_unix": "1593614038",
    "last_updated_utc""Wed, 01 Jul 2020 14:33:58 +0000",
}

You can combine this use of the date parameter with that of the base_amount, to determine how much a specific amount of the base currency converted to of the target currency at a specified date in the past.

https://currency.abstractapi.com/v1/convert
    ? api_key = YOUR_UNIQUE_API_KEY
    & base = USD
    & target = SGD
    & date = 2020-01-01
    & base_amount = 500

If you specify a date in the request, the API will return the historical rate for that particular day.

{
    "base": "USD",
    "target": "SGD",
    "target": "2020-01-01",
    "base_amount": 500,
    "converted_amount": 674.14,
    "exchange_rate": 1.34827,
    "last_updated_unix": "1593614038",
    "last_updated_utc""Wed, 01 Jul 2020 14:33:58 +0000",
}

Developers around the world love Abstract's Exchange Rate API

Finally an exchange rate API that's fast, reliable, and reasonably priced! We tested several providers and loved everything about Abstract.

Jack Smelton

Abstract's Exchange Rate API has opened up entire new areas of growth for our ecommerce sites and made it very easy for us to expand internationally. It's been a huge time saver.
