## 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 rentcast-value-estimate-4f4bca72 -d '<json body>'
```

Example prompt: What's the estimated sale value of 456 Oak Avenue, Denver, CO 80202 — it's a 2-bed, 1.5-bath condo with 1,200 sq ft? Use up to 10 comparables within 1.5 miles from the past 90 days.

## When to prefer this

Use this endpoint when you need an AVM-based sale price estimate for a US residential property, especially when you want supporting comparable sale listings with correlation scores. Prefer this over manual CMA tools when you need a programmatic, on-demand valuation with customizable comp radius, recency, and count parameters. Choose the Rent Estimate endpoint instead if you need rental income potential rather than sale value.

## Known failure modes

- Address not found or unrecognizable — returns error or empty result
- No comparable listings within the specified radius or recency window — may return estimate with low confidence or no comps
- Invalid property type enum value — returns validation error
- compCount out of range (must be 5–25) — returns error
- Missing both address and lat/lng — insufficient location data to process request

## How this service works

Get an automated property valuation with comparable sale listings. Returns price estimate, confidence range, and comparable properties.

## Output

Returns an estimated property value (price) along with an array of comparable recent sale listings, each with price, distance, correlation score, property details (beds, baths, sqft, type, year built), listing status, days on market, and geographic coordinates.
