Python Client for FRED® API
===========================
Python client for interfacing with the Federal Reserve Bank's
FRED API. Our goal is to provide a simple, well-documented
solution for FRED-related programming in Python.

::

  This is a third-party client that is developed and maintained
  independently of the Federal Reserve Bank. As such, it is not
  affiliated with or supported by the institution.

Features
--------

This client was built to provide users with an intuitive
and effective framework for making requests to the FRED API
from within Python. As such, our main feature is the
ability to interact with the FRED web-service.

Comprehensive query support
~~~~~~~~~~~~~~~~~~~~~~~~~~~

Request economic data from all 5 data groups available in FRED and ALFRED.
For reference, the data groups are included below.
See `Federal Reserve Bank of St. Louis`_  for additional documentation,
or click on a specific query to go directly to documentation for that query.

Popular response transformations
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Transform data from http responses to your preferred format,
allowing you to focus more time on data integration and analysis
and less on response processing. If you prefer raw responses from FRED,
so that you can conduct your own response parsing, simply set ``response_type``
to *xml* or *json* (standard FRED responses). Otherwise, automatically
transform data into comma, tab, or pipe separated values,
python dictionaries, pandas dataframes, or numpy arrays.

For dictionary, dataframe, and array responses, an attempt is made to
convert data to more useful dtypes. For example, ``realtime_start``
and ``realtime_end`` response data are automatically converted
from a string to *datetime64* numpy dtype. Similarly, counts
and IDs (where appropriate) are converted to *int* while observation
measures are converted to *float*.
