## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability hubvibe-property-context-2d2d099c -d '<json body>'
```

Example prompt: Pull together all the federal real estate data for 742 Evergreen Terrace, Springfield, IL — I want flood risk, hazard ratings, median home value, walkability, nearby public schools within 2 km, and any Superfund sites within 5 km.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
