How this service works
Real estate data for any US address: FEMA flood and 17 other hazard risk ratings with expected annual loss, median home value, rent, income, ownership and vacancy (Census), price trend (FHFA), fair market rents (HUD), nearby public schools (NCES), walkability (EPA) and Superfund sites nearby, plus tract, county, ZIP and districts, all from federal sources in one call. Input: address, or lat and lng.
Output
A structured JSON object containing up to 18 federal-source data points for the given US address: FEMA flood risk and 17 other hazard risk ratings with expected annual loss, median home value, median rent, household income, ownership and vacancy rates (Census), FHFA price trend, HUD fair market rents, nearby public schools (NCES) with configurable radius, EPA walkability score, nearby Superfund sites with configurable radius, and geographic identifiers including census tract, county, ZIP code, and congressional/administrative districts.
Example use cases
Home purchase due diligence report
“Before I make an offer on 1420 Harbour Blvd, Fullerton, CA, can you get me all the FEMA flood and hazard risk scores, the expected annual loss, median home value, FHFA price trend, and HUD fair market rents for that address?”
Rental investment neighborhood analysis
“I'm looking at a rental property at 305 East 86th Street, New York, NY — can you get me the census median rent, household income, vacancy rate, ownership rate, and walkability score from federal data so I can evaluate the neighborhood?”
School and safety check for family relocation
“We're thinking of moving to 88 Pine Street, Portland, OR — can you check what public schools are within 1.5 km, whether there are any Superfund sites nearby, and what the hazard risk ratings look like for that address?”
Technical details
Endpoint
POSThttps://hubvibe-io.com/work/property/context?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-call aggregation of multiple federal real-estate data sources for a US address. It replaces separate calls to FEMA, Census, FHFA, HUD, NCES, and EPA APIs. Ideal for property due diligence, investment analysis, relocation research, insurance risk assessment, or any workflow that needs authoritative government-sourced property and neighborhood data without building custom integrations to each federal agency.
Side effects
- Address not found or cannot be geocoded — returns error indicating unresolvable address
- Address outside US coverage (lat/lng out of range 17-72N, 64-180W) — returns validation error
- school_radius_km or superfund_radius_km outside allowed bounds (0.1–5 or 0.1–15 km) — returns schema validation error
- Payment failure or insufficient USDC balance — returns 402 Payment Required
- Federal data unavailable for a specific tract or region — partial data returned or field null
- Malformed address string under 5 or over 200 characters — rejected by input validation
