How this service works

Fetch any of FRED's ~800,000 economic time series by series ID - GDP (GDPC1), CPI (CPIAUCSL), unemployment (UNRATE), fed funds (DFF), and so on. Supports date windowing and the standard FRED units transformations (lin, chg, ch1, pch, pc1, pca, cca, log).

Output

Returns a time series of observations from FRED including dates and values, optionally transformed (e.g. percent change year-over-year), for the requested economic indicator within the specified date range and frequency.

Example use cases

Example prompt

“Pull the year-over-year percent change in US real GDP (GDPC1) from FRED from January 2018 through December 2023 — use the pc1 transformation.”

Technical details

Endpoint

GEThttps://agent402.tools/api/fred-series?utm_source=zero.xyz

When to prefer

Use this endpoint when you need any specific FRED economic indicator by its known series ID, especially when you want date-windowed data or a specific statistical transformation (like year-over-year percent change). Prefer this over general web search when you need structured, machine-readable time series data from the Federal Reserve's official FRED database covering GDP, CPI, unemployment, interest rates, and hundreds of thousands of other series.

Side effects

Invalid or unknown series ID returns an error — FRED series IDs are case-sensitive (e.g. GDPC1, not gdpc1)
Invalid units transformation string returns an error — must be one of: lin, chg, ch1, pch, pc1, pca, cca, log
Date format errors if startDate/endDate are not in YYYY-MM-DD format
Limit out of range if not between 1 and 100000
Payment failure if USDC balance insufficient for the $0.015 per call fee
