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 the latest data point for the requested FRED series, including the series ID, the latest observation object (with date and value), and the data source attribution string.
Example use cases
Inflation monitoring dashboard
“Get me the latest CPI inflation reading from FRED — the series is CPIAUCSL — so I can update our economic dashboard.”
Interest rate research report
“What's the current federal funds effective rate? Use FRED series DFF and give me the latest data point for my rate analysis.”
GDP growth tracking

Technical details
Endpoint
POSThttps://frederalfathom.vercel.app/api/latest?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the single most recent value from any of FRED's 816,000+ macroeconomic time series — GDP, unemployment, inflation, interest rates, housing, trade, and more — without building a FRED API integration yourself. It is ideal for quick spot-checks of current economic conditions rather than full historical series retrieval.
Side effects
- Invalid or nonexistent FRED series ID returns an error or empty result
- Network timeout if FRED upstream is slow
- Missing required seriesId field returns a validation error
- Series with no recent observations may return an empty latest object
- Payment failure via x402 protocol blocks the request
