Technical details
Endpoint
GEThttps://oracles-production.up.railway.app/v1/econ-fed-funds/changesWhen to prefer
Choose this endpoint when you need structured, machine-readable FRED observations of the effective federal funds rate with significance filtering and change detection — especially for monitoring workflows that need to detect new rate prints since a known timestamp. Prefer over general FRED wrappers when you need the change-detection framing, significance scoring, and ISO-8601 time-bounded queries.
Side effects
- FRED_API_KEY not set — endpoint no-ops and returns empty or error response
- Invalid ISO-8601 format for 'since' parameter returns a 400 validation error
- limit out of range (less than 1 or greater than 500) returns a 400 error
- min_significance out of range (less than 1 or greater than 10) returns a 400 error
- No new observations since the provided timestamp returns an empty changes array
- Upstream FRED API unavailable causes a 502 or timeout response
