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 release date objects for the specified FRED release, along with the release ID and source attribution. Each date entry indicates when that economic data release was published or is scheduled to be published.
Example use cases
Track CPI inflation report schedule
“What are the historical release dates for the Consumer Price Index report on FRED? The release ID is 10 — give me the last 15 dates.”
Monitor GDP data publication calendar
“Look up when the GDP data releases have come out historically using FRED release ID 53, and show me the most recent 20 release dates.”
Align investment model with data releases
“I need to know the release dates for FRED release ID 175 — fetch the last 10 dates so I can align my model updates with when the data actually comes out.”
Technical details
Endpoint
POSThttps://fathoms.vercel.app/api/release-datesWhen to prefer
Use this endpoint when you need to know the historical or scheduled publication dates for a specific FRED economic data release — for example, to time data ingestion pipelines, align model updates with data availability, or audit when a particular macroeconomic series was last updated. Prefer this over general FRED browsing when you already know the release ID and need its date history.
Side effects
- Missing or invalid releaseId returns an error or empty result
- Non-existent FRED release ID returns no data or an error
- Exceeding rate limits or payment failures result in rejection
- Limit parameter ignored or defaulted if malformed
