Data Feed

The Data Feed provides HTTP(S) access to a single file containing exchange rate information. The file format (XML, CSV, JSON, etc.) and content options (base unit, language for currency names, additional properties, etc.) are indicated by setting query fields in the access URL. An FTP write option is available upon request.

The general access format is:

https://fx.currencysystem.com/v5/?arguments

For example:

https://fx.currencysystem.com/v5/?licensekey=1234&format=XML

The supported arguments are:

  • LicenseKey: Data Feed service subscription license key (this is the only required argument)
  • Format: XML, INI, JSON, JSONP, TSV, CSV (default is INI)
  • BaseCurrency: EUR, USD or any other supported currency (default is EUR)
  • CurrencyNames: Boolean value indicating whether the output should include currency names (default is True)
  • CurrencySymbols: Boolean value indicating whether the output should include currency symbols (default is False)
  • CountryNames: String value indicating whether the output should include country names. Possible values: False (default), Official (for extended official names) or Short (commonly used short names)
  • SmallestUnit: Boolean value indicating whether the output should include the smallest unit for each currency (default is False)
  • Regime: Boolean value indicating whether the output should include the regime identifier for each currency (default is False)
  • Language: Language for currency names (EN for English, default)
  • TitleStyle: Boolean value indicating whether title style capitalization should be used in the currency names (default is True)
  • DateOnly: Boolean value indicating whether the time stamps should include only the date (no time, while the default is date and time)
  • Date: Reserved for future use (currently must be omitted or be set to an empty value)
  • Type: Reserved for future use (currently must be omitted or be set to an empty value)
  • Unique: Ignored as a feed option, but may be used to insert a unique (sequential or random) portion to minimize possible caching by intermediate proxy servers (which may otherwise serve a copy of previous data)

Multiple semicolon-separated BaseCurrency values are allowed, in which case the result will include additional cross-rate combinations. The arguments match equivalent options in the managed Web Service, where the interface is documented in more detail.

A yearly subscription to the managed Data Feed for up to 10 accesses/day can be activated in the Purchase section. Fetching the entire set of rates counts as a single access. For more information:
