ZeroPointRepo zillow-zestimate
Single-purpose valuation skill. Fire only on an explicit valuation request. When the intent is ambiguous, confirm with the user first: calls consume credits.
If the user also wants photos, schools, agent contact or price history, use zillow-full instead.
Tool
get_zestimate (1 credit)
Pass either zpid (preferred: cheaper, cache-served) or address. With only address, the handler resolves the zpid first.
Returns:
{
"data": {
"zestimate": 489500,
"rent_zestimate": 2800,
"tax_assessed_value": 410000,

"currency": "USD"
}
}
