How this service works
Free macroeconomic data API powered by FRED. 816,000+ economic time series. GDP, inflation, unemployment, interest rates, and more.
Output
An array of release date objects for the specified FRED release, along with the release ID and source attribution string. Each item in the dates array contains date metadata indicating when that release was or will be published.
Example use cases
Track CPI Inflation Report Schedule
“When has the CPI inflation report been released this year? Pull the release dates from FRED for release ID 10, last 12 entries.”
Monitor GDP Data Publication Calendar
“I need to know the upcoming and past release dates for the US GDP report on FRED — can you look up release ID 53 and show me the 10 most recent dates?”
Verify Federal Funds Rate Data Freshness
“Check when the Federal Reserve's interest rate data has been published on FRED — look up release ID 18 and give me the last 5 release dates so I know how current the data is.”
Technical details
Endpoint
POSThttps://fathom-opal.vercel.app/api/release-datesWhen to prefer
Use this endpoint when you need to know the publication schedule or history for a specific FRED economic data release — for example, to track when GDP, CPI, unemployment, or interest rate reports are issued. Prefer this over general economic data endpoints when the question is specifically about *when* data is released rather than *what* the data values are.
Side effects
- Invalid or nonexistent releaseId returns an error or empty dates array
- Missing required releaseId field results in a validation error
- Limit parameter out of range may return default or error
- Upstream FRED API unavailability causes failure or stale data
- Payment failure (x402 protocol) prevents request from completing
