How this service works
Free macroeconomic data API powered by FRED. 816,000+ economic time series. GDP, inflation, unemployment, interest rates, and more.
Output
A JSON object with a 'source' field (e.g. 'FRED') and a 'results' object keyed by series ID, each containing recent observations (date and value pairs) for the requested economic time series.
Example use cases
Macro dashboard for investment research
“Grab the last 8 data points for GDP, UNRATE, CPIAUCSL, and FEDFUNDS from FRED — I want a quick snapshot of the macro environment for my investment memo.”
Inflation and jobs brief for weekly report
“Fetch the 5 most recent observations for CPIAUCSL and UNRATE so I can summarize where inflation and unemployment stand for this week's economic briefing.”
Interest rate comparison across indicators
“Pull the latest 12 observations each for FEDFUNDS, DGS10, and DGS2 from FRED — I need to see the short and long end of the yield curve alongside the Fed Funds rate.”

Endpoint
POSThttps://fathom-opal.vercel.app/api/bulkWhen to prefer
Choose this endpoint when you need multiple FRED economic series in a single API call rather than making individual requests per series. It is ideal for macro dashboards, economic research agents, and any workflow requiring correlated indicators (e.g. GDP + inflation + unemployment together). Prefer it over single-series endpoints when batching 2+ FRED series, and over direct FRED API access when you need a simple pay-per-use wrapper without managing API keys.
Side effects
- Invalid FRED series ID returns an error or empty result for that series
- Network or upstream FRED API unavailability causes request failure
- Requesting too many series in one call may cause timeouts
- Malformed request body (missing seriesIds array) returns a 400-level error
- Payment failure (insufficient USDC) blocks access
