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 with a source field (identifying FRED as the data provider) and a results object keyed by series ID, each containing the requested number of time-stamped observations with their values for the requested economic indicators.
Example use cases
Recession risk dashboard
“Fetch the last 20 observations each for GDP, UNRATE, T10Y2Y, and USREC from FRED so I can track recession indicators in one place.”
Inflation research report
“Get me the 12 most recent data points for CPIAUCSL, CPILFESL, and PCEPI from FRED — I need headline CPI, core CPI, and PCE inflation for a comparison report.”
Central bank policy briefing
“Retrieve the last 8 observations for FEDFUNDS, DGS10, and DGS2 from FRED so I can summarize where the Fed funds rate and Treasury yields stand right now.”
Technical details
Endpoint
POSThttps://fredfathom.vercel.app/api/bulk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to fetch data for multiple FRED economic series in a single call rather than querying them one at a time. It is ideal for dashboards, research workflows, or any agent task requiring several macroeconomic indicators simultaneously. Prefer it over single-series endpoints when batching GDP, CPI, unemployment, interest rates, or any of the 816,000+ FRED series together is more efficient.
Side effects
- Invalid or non-existent FRED series ID returns an error or empty result for that series
- Malformed seriesIds array (non-array type) triggers a validation error
- Network timeout on the upstream FRED API causes a failed response
- Requesting too many series simultaneously may degrade response quality or trigger upstream rate limits
- Missing required seriesIds field returns a 400-level error
