Frequently Asked Questions

Drop us an email if you couldn't find an answer to your question in the following list

What is Owo API?
Owo API provides a JSON-based REST API, delivering reliable and accurate currency exchange rates for 200 world currencies and precious metals at an affordable price, which makes it the perfect instrument for startups and online businesses, as well as for larger companies in need of reliable financial data via an easy to use interface. The Owo API is widely used to power financial departments, mobile applications and back-office systems around the world.
How accurate is Owo API forex data, and where does it come from?
Our exchange rates are sourced from a very broad base of commercial sources and banks around the world, each of varying types and frequencies. The larger weighting particularly for major currencies is towards commercial sources as they more accurately reflect the trading occurring in the markets. In order to ensure the highest possible level of data coverage and liquidity, the Owo API system relies on a very distinct “validation and fallback” algorithm, assigning different priorities to each data source and validating each forex rate as it enters our databases. If a source fails to deliver an accurate quote, the next highest provider is queried for this particular currency pair. This enables us to sort out possible inaccuracies and provide the vast majority of all spot exchange rates with a precision of six decimal places.
How often are exchange rates refreshed?
Our exchange rate data is collected within the 60-second market window. Depending on your Subscription Plan, quotes are refreshed every 60 minutes (Free Plan), 30 minutes (Standard Plan), or 60 seconds (Enterprise Plan).
Which currency data does the API provide?
Depending on which API endpoint you are using for your query, the Owo API will return or calculate with the most representative forex market rate available, which is generally the "midpoint" value. The "mid" value will also be the most useful tool to your company's financial department for accounting & invoicing purposes, for financial estimates or planning, for calculator & converter applications, and for any other applications you power with Owo API forex data.
Which currencies and precious metals are supported by the API?
The Owo API provides real-time and historical data for a total of 200 world currencies and precious metals (including Gold "XAU" & Silver "XAG"). A more detailed list of all supported currencies will soon be available. Does the API support Bitcoin (BTC)? Yes. Real-time exchange rate data for Bitcoin (listed as BTC) is available via every API Endpoint. However, please be aware that, at this stage, historical Bitcoin data is only available from 2012-12-10 onwards. At which time are historical exchange rates made available? The previous day's historical exchange rates become available each day at 00:05 AM GMT (12:05 AM London time). However, to allow for reverse rate conversions and consistent comparisons, all rates are time stamped at 23:59:59 GMT. All timestamp values returned by the API are standard UTC timestamps.
