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 object containing the FRED series metadata (info object), the series ID, and a source attribution string. The info object likely contains the time series observations, units, frequency, and descriptive metadata for the requested economic indicator.
Example use cases
Tracking inflation for investment thesis
“Can you fetch the FRED CPI series — the series ID is CPIAUCSL — so I can analyze recent US inflation trends for my portfolio review?”
Monitoring GDP growth for economic report
“Get me the latest US GDP data from FRED using the series ID GDP — I need it for a macroeconomic summary I'm writing.”
Comparing interest rate history
“Pull the federal funds rate time series from FRED — the series ID is FEDFUNDS — so I can chart how rates have changed over the past decade.”

Endpoint
POSThttps://fredfathom.vercel.app/api/series?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic access to any of FRED's 816,000+ macroeconomic time series without setting up a FRED API key. Ideal for agents performing economic research, financial analysis, or data enrichment tasks where the specific FRED series ID is known. Prefer this over direct FRED API calls when operating in a pay-per-use agent context using x402 micropayments.
Side effects
- Invalid or unknown FRED series ID returns an error or empty result
- Missing required seriesId field causes a validation error
- FRED upstream API downtime may result in failed responses
- Misspelled series IDs (e.g. 'GDB' instead of 'GDP') will not return data
- Payment failure (x402) blocks the request before it reaches FRED
