What (One-liner)
Any FRED series, relayed exactly as published on the engine lane — so server-side scripts and diff nodes can consume it — with the actual window declared, never padded.
How to use
Set the FRED series id (e.g. BAMLH0A0HYM2 / DGS1 / VIXCLS) + lookback and run. Wire it into script nodes (bind values / dates_ord / latest). Note: FRED keeps only a trailing window for some licensed series (e.g. ICE BofA OAS ~3y) — the returned window is declared via date_min/date_max.
Input / Output contract
Inputs: series_id, lookback_days (a request — the actual window is what FRED holds).
Output: values/dates/dates_ord (oldest→newest), latest, n_dates, date_min/date_max, source. No symbol field by design.
Known limitations
- Relay only — every derived statistic belongs downstream.
- Licensed series carry limited windows; declared, never padded.
