## How to call it through Zero

## When to prefer this

Use this endpoint when an agent needs a quick, data-backed property valuation with comparable sales and negotiation context for a specific address — particularly useful during home buying, selling, or investment analysis when the user wants to know fair market value and how to negotiate effectively.

## Known failure modes

- Property address not found or not recognized — returns error or null valuation
- Insufficient comparable sales data in the area — low-confidence AVM estimate
- Invalid or malformed address input — returns validation error
- Payment of 0.1 USDC not processed — returns 402 Payment Required
- Property in a rural or sparse market — comps may be limited or unavailable

## How this service works

Property valuation and home value estimate (AVM): estimated value with confidence range, price per square foot, comparable sales, days-to-sell estimate, and negotiation intelligence for any address. For homebuyer, seller, and real-estate agents.

## Output

Returns an automated valuation model (AVM) estimated property value, a set of comparable recent sales in the area, and negotiation intelligence such as whether the property is priced above or below market, giving the agent data to advise on offer strategy.
