Freddo

This is an opinionated library for accessing the Federal Reserve of St Louis data API. It may not implement all the functionalities of the API.

For a like-for-like implementation of the API in Rust, see fred-rs.

Pre-requisites

• You will need an API key that can be generated here
• To use the library, store the API key as the environment variable FRED_API_KEY

General structure

• A client stores the API key and the base URLs that are needed to interact with the API
• The use of the library starts with the construction of a query
• Each query belongs to one of the three types:
  • data which obtains the actual observations
  • search which allows the user to search for data series using key words
  • info which obtains the metadata related to a data series
• Each query has an execute method to carry out the request
