How this service works
Return point-in-time-safe history for one curated series using ALFRED realtime dates. Use this for backtests or retrospective questions where revised history would be misleading.
Output
A time series of historical values for the specified FRED macroeconomic series as they existed at a given realtime (vintage) date, including original release figures without subsequent revisions, enabling point-in-time-safe analysis and backtesting.
Example use cases
Backtest with unrevised GDP data
“Get me the vintage history for FRED series GDP as it was known on 2019-01-01 — I'm running a backtest and need the original unrevised values, not the current revised ones.”
Retrospective inflation analysis
“Fetch the point-in-time ALFRED history for CPIAUCSL as of realtime date 2022-06-01 so I can analyze what inflation data looked like to policymakers at that moment.”
Avoid look-ahead bias in macro model
“I'm building a macro factor model and need the FRED series PAYEMS employment data exactly as it was reported on 2018-09-01 — give me the vintage history so I don't accidentally use revised numbers.”

Endpoint
POSThttps://mesh.heurist.xyz/x402/agents/FredMacroAgent/macro_vintage_historyWhen to prefer
Choose this endpoint when you need macroeconomic data exactly as it was known at a specific historical moment — critical for backtesting trading strategies, building factor models, or conducting retrospective policy analysis where using revised data would introduce look-ahead bias. Prefer this over standard FRED endpoints whenever historical accuracy at a point in time matters more than the most current revised values.
Side effects
- Invalid or unknown FRED series ID returns an error or empty result
- Realtime date outside available ALFRED vintage range returns no data
- Malformed date format causes a request validation error
- Series with no revisions history may return identical data to current FRED
- Network timeout or upstream ALFRED API unavailability causes 5xx error
