Exchange rates API FAQs

OANDA Rates are accurate and reliable. We have been providing Rates data for 25 years, and our rates are trusted by tax authorities, auditing firms, thousands of companies and millions of individuals globally. There are over 190 currencies and commodities, with over 38,000 pairs available. Our historical rates date back to 1990, making us the world's most comprehensive FX data provider.

Our rates are easy to use/implement into your system. Our automated FX data feed plugs OANDA® Rates and our historical currency converter directly into your ERP or proprietary system.

The exchange rates provided by OANDA are averages from the global foreign exchange market gathered from frequently updated sources, including our OANDA fxTrade currency trading platform, leading market data vendors, and contributing financial institutions. Most of our rates are based on tens of thousands of different price points, collected every tick, every second, 24 hours a day, 365 days a year. Our state-of-the-art technology then validates rates and detects/filters anomalies using algorithms, and calculates the average of all collected data over a 24-hour period to make it available to our customers.

OANDA's FX rates are derived from constantly updating sources, including our OANDA fxTrade currency trading platform, leading market data vendors, and contributing financial institutions. FX is an over-the-counter (OTC) market, which means that OTC contracts are not executed and cleared on a central exchange as you find for stocks, futures and other listed instruments. This means that the source and quality of FX rates can vary widely between data providers. OANDA's rates might differ from other data providers, as they may make use of a single source or non-tradable rates. OANDA offers actually traded foreign exchange prices to our clients and is recognised globally as the standard for accurate FX data.

You can find the API documentation here.

The exchange rate data is updated at 00:00 UTC. However, we also offer 96 fixings points daily, allowing you to customise your reporting period. For more information on how this works, please contact us.

The difference is due to the way the API and Currency Converter handle dates. The API returns either the most recently published rate or the rate for a specific date. On the other hand, when asked for a specific date, the Currency Converter returns the rate for the previous day or the most recently published rate before that date. When comparing rates, please keep this in mind when setting parameters. For example, if you want to get the average rate for Apr 1, you should set the parameter as Apr 2 on the Currency Converter page.

For information about your Historical Currency Converter or API subscription including invoices, billing history, contact details and more, please visit our Self Service Portal located HERE. You will need the primary email address on file that is associated with the subscription and the password.

As the name suggests, market rates are determined by supply and demand in the interbank market itself while central bank rates are set only by the local national bank using their internal policies and procedures.

To ensure the accuracy and timeliness of rates, we recommend re-running the job in your ERP system. If manual updates are required, you can use our development page.

Please follow these instructions to obtain the rates manually.

The first PATH PARAMETER on the page is asking for the output format. At the end of the field you can click on csv, json or xml. Most use csv since you can paste the results to Excel easily.

The QUERY-STRING PARAMETERS are:

API Key - your API key goes here

Base - currency converting from

Quote - currency converting to

Date_Time - optional but must be formatted in ISO-8601 format YYYY-MM-DD or YYYY-MM-DDThh:mm:ss±hh:mm if it is used

Fields - averages (provides daily average midpoint) are most common but select 'all' if you are not sure.

data_set - OANDA or you can use one of the other data sets that provides rates from a specific central bank if so required

Once this is all input correctly, please click on 'Try' located on the right. Slightly below that but on the left you'll see three hyper-links:

1) Response - this is where you click to get the rates to be copied to Excel.

2) Response Headers - this is something a developer would need if they are writing automation code with the API

3) Curl - this is where you will see the actual http request

To update the primary email address, please log in to our Self-Service portal (SSP) using your current primary email. Once logged in, you can easily change the email address in your account settings. If you no longer have access to the original email, please contact our Customer Support at webservices@oanda.com

In the event you reach your monthly limit of 100,000 quotes, our team can reset it for you as a one-time exception. However, if you hit the limit again, you will be prompted to upgrade your plan to accommodate your increased usage needs.

One quote is calculated as follows: 1 currency pair multiplied by 1 day.

Your quote usage count is not tied to the calendar month but instead aligns with the day your subscription was activated. To determine when your usage will reset each month, refer to the date on your invoice. For instance, if your invoice was issued on January 14th, your monthly usage will reset on the 14th of each subsequent month.

If you are experiencing issues with receiving data, we recommend the following troubleshooting steps:

Check API Availability: Verify the status of the API on our Dashboard to ensure it's operational.

Replicate the Issue: Use our development page to replicate the issue by inputting all necessary parameters.

Successful Response: If our server returns the requested rates, the issue likely lies on your end and requires internal investigation.

Error Message: If our server generates an error message, please send the following information to our Customer Support at webservices@oanda.com for further assistance:

1. The full URL of your API call.
2. The error message and/or raw response received from our server.
