Key Differences Explained#
Why Async Support Matters
FedFred enables true concurrency when downloading large batches of FRED data, dramatically improving speed. Ideal for production pipelines, real-time apps, and bulk research.
Caching and Rate Limit Handling
No need to manually throttle API calls or install external caches. FedFred includes intelligent caching and built-in 120 requests/minute throttling.
Structured Objects vs Raw JSON
Rather than returning nested dictionaries, FedFred parses responses into typed Python classes like fedfred.objects.Series, ensuring autocompletion and static type checking.
GeoFRED and Regional Data Access
FedFred uniquely supports regional economic data (state, metro, county) directly into GeoDataFrame, perfect for mapping and GIS analysis.
Backend Flexibility
You can output to Pandas, Polars, Polars-ST, or Dask, depending on your workflow’s performance needs.
