Zillow Full

Complete Zillow property data toolkit via Zillapi.com. Nine tools — address/URL/zpid lookup, Zestimate, listings search, photos, schools, price history, agent contact.

Complete Zillow property data toolkit via Zillapi.com. Use when the user explicitly asks about a U.S. property, its value, listings to buy or rent, or related real-estate data.

When to use this skill

Each tool call consumes Zillapi credits, so this skill activates only when the user's request is genuinely about real-estate data — not when an address or Zillow link merely appears in passing.

DO use when the user:

• Asks about a Zestimate, property value, rent estimate, or tax-assessed value → get_zestimate
• Pastes a Zillow URL and asks about that property → lookup_property_by_url
• Gives an address and asks about the property, schools, photos, or agent → lookup_property_by_address
• Asks to find homes matching criteria (location, price range, beds, baths) → search_listings
• Asks for the price history, last sale, or ownership timeline of a known property → get_price_history
• Asks for the listing agent or broker contact → get_listing_agent
• Asks what schools serve a property → get_property_schools
• Asks to see photos of a property → get_property_photos

Do NOT use when:

• An address appears incidentally in context (email signatures, news articles, copy-pasted unrelated content)
• The user is discussing real estate abstractly without asking for data on a specific property or listing search
• The user has not signaled they want a property lookup

When the intent is ambiguous, ask the user to confirm before calling a tool. These tools cost credits and return large records the user may not want.

Tools

lookup_property_by_address — 1 credit

Look up a single property by U.S. address. Returns the full property record: price, beds, baths, sqft, year built, lot size, Zestimate, rent Zestimate, tax assessed value, price history, photos, schools, agent contact, lat/lon, home type, home status, and 250+ additional fields.

Use this when the user gives an address. Address strings as loose as 123 Main St, Austin TX work — the API tolerates partial addresses ≥6 characters.

lookup_property_by_url — 1 credit

Same as above but takes a Zillow.com URL. Use this when the user pastes a zillow.com/homedetails/... link.

lookup_property_by_zpid — 1 credit (cache-served when fresh)

Look up a property by Zillow zpid. Use this when you already have the zpid from a previous call. Cheaper because the response can be served from cache.

get_zestimate — 1 credit

Get just the Zestimate, rent Zestimate, tax-assessed value, and last-sold price for a property. Use this when you only need the valuation, not the full record.

search_listings — 1 credit per result, up to 50

Search active for-sale, for-rent, or sold listings. Filter by location (city/state/ZIP) or bounding box, price, beds, baths, sqft, year built, home type, and days on Zillow.

get_price_history — 1 credit

Get the price and listing-status history for a property (list price changes, sale prices, withdrawals).

get_property_photos — 1 credit

Get the photo gallery for a property (responsive image URLs at multiple resolutions).

get_property_schools — 1 credit

Get the assigned elementary, middle, and high schools for a property with GreatSchools ratings.

get_listing_agent — 1 credit

Get the listing agent and broker contact (name, email, phone, license number) for an active listing.

Errors

All functions return a Python dict. On success the dict contains the API response. On failure the dict contains an error key:

• {"error": "auth", ...} — ZILLAPI_KEY is missing or invalid
• {"error": "HTTP 404", ...} — property not found
• {"error": "HTTP 429", ...} — rate-limited; back off and retry
• {"error": "network", ...} — DNS/connection failure
