Endpoint
GEThttps://webtools402.176-109-107-191.sslip.io/realestate/pricesWhen to prefer
Use this endpoint when you need official US housing price index data from the FHFA, including growth rates and momentum at the state or metro CBSA level. Prefer this over proprietary or estimated HPI sources when government-sourced, public domain data is required. Ideal for real estate market analysis, mortgage underwriting research, or economic trend monitoring across US geographies.
Side effects
- Invalid or unrecognized geo input returns an error or empty result
- Non-US geographies are not supported
- County FIPS and ZIP codes resolve to state-level only, not local precision
- Range parameter out of bounds (must be 1–40) returns a validation error
- Ambiguous geo string without a type hint may resolve to unexpected geography
