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 an array of tag objects representing available economic data categories/labels in the FRED database, along with a source identifier string. Each tag object can be used to navigate or filter the broader dataset of 816,000+ economic time series.
Example use cases
Exploring available inflation data categories
“Search the Fathom FRED-powered API for tags matching 'inflation' and give me up to 30 results so I can see what kinds of inflation data series I can pull.”
Browsing all macroeconomic data tags
“Pull the full list of available economic data tags from Fathom — give me the default 50 — so I can see what macroeconomic categories exist before I dig into specific time series.”
Finding interest rate data labels
“Look up tags in the Fathom macroeconomic database that contain 'interest rate' so I can figure out which categories cover Fed funds rate and Treasury yield data.”
Technical details
Endpoint
POSThttps://frederalfathom.vercel.app/api/tags?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover what economic data categories or labels are available before querying specific time series. It is the right starting point for navigating the FRED-powered Fathom database — particularly when the user's topic is vague and you need to identify the correct tag/category before fetching actual economic data. Prefer this over directly querying series data when you do not yet know the exact series ID or tag name.
Side effects
- Empty results if search keyword matches no tags
- Invalid limit parameter type may cause errors
- Network timeout on vercel.app cold starts
- Malformed request body returns error response
