## 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-rent-estimate-8da47907 -d '<json body>'
```

Example prompt: What's the estimated monthly rent for a 3-bedroom, 2-bathroom single family home at 123 Main St, Austin, TX 78701 that's about 1800 sq ft? Look at comparables within 2 miles from the last 90 days.

## When to prefer this

Use this endpoint when you need a data-driven rental price estimate for a specific US property, especially when you want to see the underlying comparable listings that support the estimate. Prefer this over generic AVM tools when the goal is specifically rental income estimation (not sale price). Best when you have a full address or lat/lng coordinates and property characteristics like bedrooms, bathrooms, and square footage.

## Known failure modes

- Address not found or geocodable — returns error with no estimate
- No comparable listings found within the specified radius or age window — may return null or limited comps
- Invalid property type string — returns validation error
- compCount out of range (must be 5-25) — returns error
- Missing both address and lat/lng — ambiguous location error

## How this service works

Get a long-term rental estimate with comparable rental listings. Returns monthly rent estimate, range, and comparables.

## Output

Returns an estimated monthly rent price in USD and a list of comparable active rental listings nearby, each with address, price, distance, bedroom/bathroom counts, square footage, days on market, listing status, and a correlation score indicating how similar the comp is to the subject property.
