#Xaye.Fred
Xaye.Fred is a simple .NET wrapper around the Federal Reserve Economic Data (FRED) API. The library is part of the Xaye project, but doesn't depend on any other parts of Xaye (or any other library). It is licensed under the permissive Simplified BSD license.
Available via NuGet: https://nuget.org/packages/Xaye.Fred
PM> Install-Package Xaye.Fred
To use the library, you must have a FRED API key. A key can be obtained from http://api.stlouisfed.org/api_key.html
Create a Xaye.Fred object:
var fred = new Fred("api key");
Calls using the FRED API default values:
IEnumerable<Release> GetReleases() -> http://api.stlouisfed.org/docs/fred/releases.html
Release GetRelease(int releaseId) -> http://api.stlouisfed.org/docs/fred/release.html

IEnumerable<Observation> GetSeriesObservations(string seriesId) -> http://api.stlouisfed.org/docs/fred/series_observations.html
IEnumerable<Source> GetSources() -> http://api.stlouisfed.org/docs/fred/sources.html

IEnumerable<Release> GetSourceReleases(int sourceId) -> http://api.stlouisfed.org/docs/fred/source_releases.html
The library caches calls for Categories and Series (it returns a cached version if the object has already been retrieved from the FRED database). If you don't want a Fred instance to cache them, set caching to false in the constructor
var fred = new Fred("api key", false);
If caching in enabled, you can clear it at anytime by calling ClearCache().
fred.ClearCache();
- Overloaded versions are provided so user's can override FRED's default values.
- Where properties on Release, Category, Source, and Series objects return an enumeration, the enumeration is lazily loaded. That is, a FRED API call is not made until that property is accessed.
- .NET 4.5 asynchronous versions of the methods above are available in the project source but not the NuGet package.
