How this service works
The effective federal funds rate — the Fed's benchmark policy rate that anchors every other US interest rate — as a monthly average in percent, with the latest value, prior month, month-over-month and year-over-year change, and recent history. No ticker needed. The rate every rate-sensitive analysis starts from. Sourced from the St. Louis Fed (FRED). From x402stock
Output
Returns a JSON object containing the FRED series ID and title, unit and frequency, the latest monthly rate value with date, the prior month value with date, the absolute change, month-over-month percent change, year-over-year percent change, and an array of recent monthly historical data points (each with date and value). The as_of field indicates data freshness.
Example use cases
Mortgage rate sensitivity analysis
“I'm building a model to assess how sensitive mortgage rates are to Fed policy. Can you grab the current effective federal funds rate from FRED, including the month-over-month and year-over-year changes, so I can use it as a baseline for my analysis?”
Fed policy briefing for clients
“I need to put together a quick macro briefing for my clients on where the Fed stands right now. Pull the latest federal funds rate data, show me how it's changed over the past month and year, and include some recent monthly history so I can spot the trend.”
Inflation vs rate trend comparison
“I'm comparing inflation trends against Fed tightening cycles. What's the current federal funds rate, what was it a year ago, and can you show me the recent monthly history so I can see how aggressively the Fed has been moving?”
Technical details
Endpoint
GEThttps://x402stock.xyz/api/v1/fed-fundsWhen to prefer
Use this endpoint when you need the authoritative US federal funds rate from FRED without specifying any ticker or series ID yourself — ideal for rate-sensitive financial analysis, macroeconomic modeling, or any workflow that needs the Fed's benchmark policy rate with historical context and change metrics in a single call.
Side effects
- FRED data temporarily unavailable — upstream outage may delay refresh
- Payment failure — 402 response if USDC payment not processed
- Stale data — rate reflects last available monthly average, not real-time intraday
- No prior or change values returned if latest is the first data point in history
