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
Returns a time series of macroeconomic observations for the requested FRED series where each data point reflects the value as it was originally published at the specified vintage/real-time date, not subsequent revisions. Includes observation dates, real-time dates, and the corresponding reported values for the curated series.
Example use cases
Backtest with unrevised GDP data
“I'm running a backtest on a macro trading strategy and need historical US real GDP growth (FRED series A191RL1Q225SBEA) as it was originally reported each quarter from 2010 to 2022 — give me the vintage values before any revisions.”
Retrospective inflation analysis
“For a retrospective analysis of Fed policy decisions, pull the original CPI-U (FRED series CPIAUCSL) readings as they were known in real time from January 2018 through December 2021, using ALFRED vintage dates so I'm not seeing revised figures.”
Point-in-time unemployment for model validation
“I need to validate my recession model using data that was actually available at the time — can you fetch the FRED unemployment series UNRATE with ALFRED real-time dates for the period from 2007 to 2010, preserving the original vintage values as released?”
Technical details
Endpoint
POSThttps://mesh.heurist.xyz/x402/solana/agents/FredMacroAgent/macro_vintage_historyWhen to prefer
Choose this endpoint when you need historically accurate, unrevised macroeconomic data for backtesting or retrospective studies — situations where using revised/current FRED data would introduce look-ahead bias. Prefer this over standard FRED data fetches whenever the original as-released values matter, such as in strategy backtests, Fed policy retrospectives, or any analysis that must reflect what was actually known at a given point in time.
Side effects
- Invalid or unsupported FRED series ID returns an error
- Requested vintage date outside available ALFRED history returns empty or error
- Malformed date range parameters cause validation failure
- Network or upstream ALFRED API unavailability causes timeout
- Insufficient USDC balance for x402 payment fails the request before execution
