GET /realestate/prices
live
The FHFA House Price Index for a geography: the current index level plus year over year, quarter over quarter and five year growth, with momentum flags and a short history. State and metro CBSA levels are covered directly; county and ZIP resolve to the state level index. Public domain, US only.
Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
