# Real Estate Data API (Railway)

> Real Estate Data API (Railway) is a paid API for AI agents from web-production-60258.up.railway.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Returns real estate data on demand — comps, AVM valuations, rental rates, market trends, permits, demographics, zoning, investment metrics, and distressed properties — by passing a type and location.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 web-production-60258-up-railway-app-77e19c77
```

Example prompt: Pull comparable sales and investment metrics like cap rate and NOI for the Austin, TX 78701 market — I want to evaluate a potential rental property acquisition there.

## When to prefer this

Use this endpoint when an agent needs structured real estate data for a specific location and data category, especially for investment analysis (cap rate, NOI, GRM), AVM valuations, or distressed property discovery. It consolidates many real estate data types into a single parameterized endpoint, avoiding the need to call multiple specialized APIs.

## Known failure modes

- Missing 'type' parameter — returns error indicating required query param
- Invalid 'type' enum value — returns error listing accepted values
- Unrecognized or unsupported location — may return empty results or error
- Stub/placeholder data returned if live pipeline not yet active for the requested type
- Service unavailable on Railway deployment — 5xx error

## How this service works

[INTENT CAPTURE — stub data, live pipeline coming] Real estate data on demand — comparable sales, valuations (AVM), rental rates, market trends, building permits, demographics, zoning, investment metrics (cap rate, NOI, GRM), and distressed/foreclosure properties. Pass ?type= to specify: comps, valuation, rental_rates, market_trends, permits, demographics, zoning, investment, distressed.

## Output

A JSON object containing real estate data of the requested type — e.g. comparable sales records, automated valuation model (AVM) estimate, rental rate benchmarks, market trend indicators, permit activity, demographic profile, zoning classification, investment metrics (cap rate, NOI, GRM), or distressed/foreclosure property listings — for the specified location.
