search_transactions
Read-only
Query 8M+ Polish notarial real estate transactions by location, price, date, area, or type; get address, price, area, and price per m². Use TERYT codes for exact matches.
Instructions
Search Polish real estate transactions from the national RCN registry (8M+ records). Returns transaction details: address, date, price, area, price/m², property type. Call list_locations(search=...) first to resolve a place: prefer the returned TERYT code as teryt= (exact administrative match). Pass a name to location= only when the result flags it as an RCN district (rcn_district) — most TERYT names are not valid location= values and silently return zero rows. Example: search for apartments in Mokotów sold in 2024 above 500,000 PLN. Data notes: marketType is NULL for ~55% of records (notary didn't classify) - filtering by marketType excludes them. ~1.7% of records have no transaction_date. Permalink: every result is shareable on the map. From a result's "id:" line and its "Location: °N, °E" line, build https://cenogram.pl/ceny-transakcyjne?src=mcpstdio#v=1&lat=&lng=&z=16&tx= (drop the °N/°E; lat = the °N number, lng = the °E number) — opens that exact transaction on the map. Omit &tx= for the area only. Field provenance: values are from the notarial deed (RCN) by default; computed values (parcel area summed across plots or converted from hectares, an inferred/reclassified property type) and approximated streets are flagged inline with a neutral [...] note. Location matches TERYT districts only - for neighborhoods (osiedla), use search_by_area instead.
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| page | No | Page number for pagination (default: 1) | |
| sort | No | Sort by field (default: date) | date |
| floor | No | Floor of the unit (piętro lokalu, residential). Multi-select buckets: exact integers incl. '0' (parter) and negatives e.g. '-1' (basement), 'Nplus' e.g. '10plus' = 10 or more, '0plus' = ground and above, 'unknown' = no floor recorded (NULL). E.g. ['0','1','2'] for ground-to-2nd floor. Building storeys are a different attribute. Without 'unknown', rows with no floor are excluded. | |
| limit | No | Number of results (1-50, default 10) | |
| order | No | Sort order (default: desc) | desc |
| rooms | No | Number of rooms (izby) filter, residential units only. Multi-select; '8plus' means 8 or more, 'unknown' = no room count recorded (NULL). E.g. ['2','3'] for 2-3 izby flats. Without 'unknown', rows with no room count are excluded. | |
| teryt | No | TERYT administrative code(s) for precise area filtering. Comma-separated, max 10. 2-digit (voivodeship), 4-digit (county), 6-digit (municipality), or full precinct code (e.g. '321705_2.0054'). Use list_locations to find codes. More precise than 'location' - avoids name ambiguity. | |
| dateTo | No | End date (YYYY-MM-DD) | |
| street | No | Street name filter, matched anywhere inside the name (e.g. 'Puławska', 'Aleja Waszyngtona'). Give it in the NOMINATIVE and with its Polish diacritics — matching is literal, so 'Karmelickiej' does not find 'Karmelicka' and 'Marszalkowska' does not find 'Marszałkowska'. Either mistake answers with nothing, which reads exactly like 'no such transactions'. | |
| landUse | No | Recorded land-use category of the transaction's land. Multi-select from: gruntyZabudowaneIZurbanizowane (built-up and urbanised), gruntyRolne (agricultural), gruntyLesne (forest), terenyKomunikacyjne (transport), inne (other). 'unknown' = no category recorded for the land (NULL) — a legitimate bucket, never a claim that the land has no use. Values are case-sensitive. E.g. ['gruntyRolne'] for farmland, or ['gruntyZabudowaneIZurbanizowane','gruntyRolne'] to compare developed vs farmland. | |
| maxArea | No | Maximum area in m² | |
| minArea | No | Minimum area in m² | |
| dateFrom | No | Start date (YYYY-MM-DD) | |
| location | No | Location name - city (e.g. 'Warszawa', 'Kraków', 'Gdańsk') or district (e.g. 'Mokotów', 'Kraków-Podgórze'). 'Warszawa', 'Kraków', 'Łódź' auto-expand to all sub-districts. Prefer teryt= for exact matches; call list_locations(search=...) to confirm a name is valid here — it flags valid ones as rcn_district. | |
| maxPrice | No | Maximum price in PLN | |
| minPrice | No | Minimum price in PLN | |
| parcelId | No | Exact parcel ID as returned in search results (e.g. '146518_8.0108.27'). Must match exactly - copy from a previous search result's parcel_id field. | |
| floodRisk | No | Flood-hazard filter. high = most frequent flooding (~1-in-10-year), medium (~1-in-100-year), low = rarest (~1-in-500-year). Selects ONLY transactions whose land sits in a mapped flood zone; absence of a zone is never asserted as 'safe'. Multi-select; e.g. ['medium','high'] = at least medium risk. | |
| marketType | No | Market type: primary (developer) or secondary (resale). ~55% of records have unknown market type and will be excluded when this filter is used. | |
| buildingType | No | Building type filter (PKOB classification). 'unknown' = no type recorded (NULL); without it such rows are excluded (~39% of buildings have no type). | |
| propertyType | No | Property type filter | |
| unitFunction | No | Unit/apartment function filter. 'unknown' = no function recorded (NULL); without it such rows are excluded. Garages appear only when 'garage' is selected, not via 'unknown'. | |
| landslideRisk | No | Landslide-hazard filter, from official landslide-hazard maps (1:10,000 scale). 'landslide' = the land intersects a mapped landslide area; 'threatened' = an area threatened by mass movements. Selects ONLY transactions whose land intersects a mapped hazard area — an intersection means overlap with a mapped area, not that the parcel itself is a landslide; absence of a zone is never asserted as 'safe'. Multi-select; e.g. ['landslide','threatened'] = any mapped hazard. | |
| ownershipType | No | Ownership / legal-right type filter (rodzaj prawa do nieruchomości). land_ownership; perpetual_usufruct (użytkowanie wieczyste — covers both registry codes for this right); cooperative_ownership; unit_sale; ownership; unit_ownership_with_appurtenant_right; building_ownership_with_appurtenant_right. 'unknown' = no right recorded (NULL). Multi-select; e.g. ['land_ownership','perpetual_usufruct'] to compare ownership vs perpetual usufruct on undeveloped land. | |
| buildingNumber | No | Building/house number (e.g. '30', '12A'). Requires location or street to be set. | |
| heritageStatus | No | Heritage-listing filter. listed = a protected monument on/at the property's land; zone = the land lies within a protected urban layout or the designated surroundings of a monument. Selects ONLY transactions where a listing was detected; absence of a detection is never asserted as 'not listed'. Multi-select; e.g. ['listed'] = individually listed properties only. | |
| buildingStoreys | No | Number of above-ground storeys of the building. Multi-select buckets: exact non-negative integers (e.g. '1','2'), 'Nplus' e.g. '3plus' = 3 or more, 'unknown' = no storey count recorded (NULL). Recorded ONLY for single-building transactions, so 'unknown' covers BOTH a deed with several buildings (no single storey count exists) and a single building with missing data — never read it as 'a building with no storeys'. This is NOT the floor of a unit (see floor). Without 'unknown', rows with no storey count are excluded. | |
| mpzpDesignation | No | MPZP zoning designation filter (exact match, e.g. 'budownictwoMieszkanioweWielorodzinne', 'terenObiektowProdukcyjnychSkladowIMagazynow'). Use 'unknown' for rows with no designation recorded (NULL); distinct from the registry code 'brakMPZPLubWZ' (= 'no plan/WZ' recorded as data). | |
| transactionType | No | Transaction type filter. For market analysis, ALWAYS specify transactionType to exclude non-market transactions (subsidized, foreclosure, public purpose). ~2% of transactions have unknown type (NULL) and are excluded when this filter is used unless 'unknown' is included. | |
| maxFootprintArea | No | Maximum building footprint (ground-plan) area in m², summed over all buildings of the transaction. Distinct from maxArea, which measures usable floor area (units) or land/parcel area. Set only where every linked building has footprint data, so this bound selects only measured rows — absence means 'not measured', not 'no building'. | |
| minFootprintArea | No | Minimum building footprint (ground-plan) area in m², summed over all buildings of the transaction. Distinct from minArea, which measures usable floor area (units) or land/parcel area. Set only where every linked building has footprint data, so this bound selects only measured rows — absence means 'not measured', not 'no building'. |
