GET /api/fred-release-observations

live

Bulk-fetch observations for every series in a FRED release in one call. Use it to grab an entire economic report (jobs report, CPI report, GDP release) without enumerating constituent series IDs first. Returns paginated; pass lastSeriesId + lastObservationDate back to fetch the next page.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
