The service from the New York Federal Reserve Bank provides historical data for foreign exchange transactions and exchange rates. The list of data available covers many of the world's currencies, with both spot and buying prices quoted at different times of day. The authoritative provider makes the data available for ingestion to automated processes that must compare currencies to calculate prices for cross-border transactions, in addition to historical research uses.
API methods support retrieval of regularly updated data formatted in compliance with the emerging Statistical Data and Metadata Exchange (SDMX) standard. URL-based access delivers data for specific currencies, with both 10 a.m. and noon quotes available for many frequently traded currencies.
The following is a list of sample source code snippets that matched your search term. Source code snippets are chunks of source code that were found out on the Web that you can cut and paste into your own source code. Whereas most of the sample source code we've curated for our directory is for consuming APIs, we occasionally find something interesting on the API provider side of things. If you know of some sample source code that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
