## Tools (19)

- `zillow_autocomplete_places`: The regions Zillow knows for a partial place name — cities, ZIPs, neighborhoods, counties — each with its region id, type and centre. What a search box needs before zillow_search_listings, and the way to a regionId.
- `zillow_building`: A rental building — name, address, description, amenities, unit and floor-plan counts, rent range and photos — by buildingId (from a forRent search row with resultType propertyGroup) or by lat and lng.
- `zillow_comps`: The comparable homes Zillow uses to value this one — each with zpid, address, price, beds, baths, living area, distance and sale date where sold.
- `zillow_floor_plans`: Every floor plan of a rental building — name, beds, baths, square feet, rent range, lease term — and the units available under each, with unit number, price, square feet and move-in date. Compact drops photo and tour links; expand true keeps them.
- `zillow_listing_agent`: The listing agent's full profile for a listed home — name, license, phone, email, website, brokerage, bio, social links, Zillow rating and review count — with the broker and the MLS id. Agent fields are null on a home with no active listing. Personal data: handle it as such.
- `zillow_market_stats`: Monthly market statistics for a region, newest first: market temperature with Zillow's buyer/seller label, for-sale inventory, new listings, new pending, median days to pending, and the share sold above and below list — up to 100 months. Give location (a place name) or regionId; `latest` carries the newest row of each series.
- `zillow_mortgage_rates`: Today's mortgage rates as Zillow lists them — product (30-year fixed, FHA, VA, 15-year, ARMs), rate and APR, with Zillow's tag for each.
- `zillow_nearby_homes`: Homes Zillow shows near this one, each with zpid, address, price, beds, baths, living area and status.
- `zillow_photos`: The photo gallery for a home — one URL per photo, in order, with the hero photo first. size full adds every size Zillow serves for each photo.
- `zillow_price_history`: Every listing, price cut, pending, sale and delisting Zillow records for a home, newest first, with the price, the change and the source.
- `zillow_property`: The record for any zpid, listed or off market — every zpid has one. Compact: the headline (status, price, Zestimate, rent Zestimate, address, coordinates, beds, baths, living area, year built, home type, lot, HOA, days on Zillow, hero photo). expand true: everything — 23 facts, price and tax history, schools with ratings, listing agent and broker, MLS, walk/transit/bike scores, nearby homes, open houses, description and the photo gallery (~17 KB).
- `zillow_property_facts`: The facts for one home: beds, baths, living area, lot, year built, home type, parking, heating and cooling, HOA, price per square foot, and the rest of Zillow's fact sheet — with the current status and price.
- `zillow_region`: A place name resolved to Zillow's region — id, type, parent state and city, centre and the exact bounding rectangle search uses — or a region id described. Give location or regionId.
- `zillow_schools`: The schools assigned to a home — name, level, grades, distance and GreatSchools rating.
- `zillow_scores`: Walk Score, Transit Score and Bike Score for a home's location, with their descriptions.
- `zillow_search_listings`: Listings for a place typed as on Zillow — a city (Austin, TX), a ZIP, a neighborhood or a county — for sale, for rent or recently sold. One row per listing with its zpid, address, price, beds, baths, living area, days on Zillow and Zestimate; up to 40 per page and 1,000 per search (page x pageSize). Rentals come back as buildings (resultType propertyGroup, with a buildingId) and single homes (property). Sort daysOn ascending for newest first.
- `zillow_tax_history`: Assessed value and tax paid by year for a home, as far back as Zillow records them.
- `zillow_top_agents`: The agents Zillow ranks around a home by sales in the past year: name, Zillow id, sales count, min/max/average/median sale price, sales in this price range, bio and profile. Who actually sells here.
- `zillow_zestimate`: The Zestimate for any zpid, listed or not: the value with its low and high, the value 30 days ago, the rent Zestimate, and zestimateHistory — one point a month for about ten years — plus the home's price history. Null where Zillow publishes no Zestimate; nothing is estimated in its place.
