## About

# zillow-zestimate

Focused valuation skill. Use only when the user **explicitly asks** for a property value — the Zestimate, rent Zestimate, tax-assessed value, or last sale price.

## When to use this skill

**DO use when the user asks:**

- "What's the Zestimate on 123 Main St?"
- "How much is my house worth?"
- "What's the rental Zestimate?"
- "What did this house last sell for?"
- "What's the tax-assessed value?"

**Do NOT use when:**

- An address appears incidentally in context (email signatures, unrelated documents)
- The user mentions a property without asking for its value
- The user has not signaled they want a valuation lookup

If you also need photos, schools, agent contact, or price history, use [`zillow-full`](https://github.com/nikhonit/zillow-skills/tree/main/skills/zillow-full) instead — it bundles everything in one install.

## Tools

### `get_zestimate` — 1 credit

Returns:

```json
{
  "data": {
    "zestimate": 489500,
    "rent_zestimate": 2800,
    "tax_assessed_value": 410000,
    "last_sold_price": 375000,
    "currency": "USD"
  }
}
```

Pass either `zpid` (preferred — cheaper) or `address`. If only `address` is given, the handler resolves the zpid first.
