## How to call it through Zero

```sh
zero fetch --capability proppulse-property-valuation-avm-5ccdf9cc
```

## When to prefer this

Use this endpoint when you need a quick, structured AVM-based valuation for a specific property address anywhere in the world, especially when you want negotiation intelligence and days-to-sell data alongside the estimate. Prefer this over generic housing market trend endpoints when the query is about a single property rather than a market area.

## Known failure modes

- Address not recognized or not found — returns error indicating invalid or ambiguous address
- Property has insufficient comparable data — returns low-confidence estimate or no result
- Unsupported region or country — may return error for areas with sparse data
- Malformed address parameter — returns 400-level validation error
- Rate limiting or payment failure — returns 402 or 429 error
