How this service works
Effective fed funds rate (Fed, monthly): latest print, revisions, surprise — Latest Effective fed funds rate print from the Fed via FRED/ALFRED: first-release vs latest value with a revised flag (revisions never pose as print-day numbers), surprise vs a labeled expectation (market-implied when a matching prediction market exists, else trend-model), next monthly release date, and a 12-observation…
Output

Example use cases
Fed policy surprise tracker
“Pull the latest effective fed funds rate data — I want to know the actual print, what the market was expecting, and whether it was a surprise. Include whether the number has been revised since first release.”
Macro dashboard refresh
“Grab the current effective federal funds rate from the Fed, along with the last 12 monthly observations and the next scheduled release date, so I can update my macro dashboard.”
Rate revision audit
“Check if the Fed has revised any of the recent effective fed funds rate readings — show me the first-release values versus the latest values for any periods that were changed.”
Technical details
Endpoint
GEThttps://x402-factory.com/v1/econ/fed-funds?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative Fed-sourced effective federal funds rate data with revision tracking and a built-in surprise calculation against market-implied or trend-model expectations. It is purpose-built for monetary policy monitoring, macro dashboards, and economic event-driven agents. Prefer it over generic FRED wrappers when you need first-release vs. revised value comparison or a pre-computed surprise metric in a single call.
Side effects
- FRED/ALFRED data temporarily unavailable — upstream data source error
- Stale data if Fed has not yet published the latest monthly release
- No market-implied expectation available — falls back to trend-model expectation source
- Malformed or empty response if the x402 payment is not processed correctly
- Rate limit or payment failure resulting in 402 response requiring USDC micropayment
