How this service works
Free macroeconomic data API powered by FRED. 816,000+ economic time series. GDP, inflation, unemployment, interest rates, and more.
Output
Returns a JSON object containing an array of tag objects associated with the requested FRED category, the category ID, and the data source identifier. Each tag object includes metadata about the tag such as its name, group ID, notes, creation date, popularity, and series count.
Example use cases
Exploring GDP data category metadata
“I want to explore FRED's GDP category — can you fetch all the tags associated with category ID 106 so I can understand what subcategories and themes are covered?”
Building a macroeconomic data taxonomy
“I'm building a catalog of economic indicators — can you get the tags for FRED category 32455 (Money, Banking, and Finance) so I can map out its data themes?”
Filtering economic series by category tags
“Before I search for time series data, I need to know what tags exist under FRED category 32992 (Interest Rates) — can you retrieve those tags so I can narrow down my query?”
Technical details
Endpoint
POSThttps://fredfathom.vercel.app/api/category-tags?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover or enumerate the metadata tags associated with a specific FRED economic category, particularly when building data catalogs, filtering series by topic, or exploring what themes are represented within a FRED category. Prefer this over general FRED series search when you already know the category ID and need its tag taxonomy rather than full time series data.
Side effects
- Invalid or non-existent category ID returns empty tags array or error
- Category ID with no associated tags returns empty array
- Malformed request missing required categoryId field returns validation error
- Rate limiting or payment failure returns 402 or 429 error
- FRED upstream service unavailability causes timeout or 503
