NATIONAL MLS DATA · RESO-STANDARD API
Live MLS listing data — listings, photos, agents, and market intel — from 250+ boards, coast to coast, through a single standards‑based interface.
One connection to the whole market — no per-board contracts, no brittle scrapes, no stitched-together datasets.
Every board we carry, delivered as it changes — status, price, photos, open houses. Refreshed continuously, so what you show is what the market is.
CONTINUOUS REFRESH · COAST TO COASTThe full picture around a listing: parcel facts, schools, district boundaries, and neighborhood demographics — the layers that turn an address into a decision.
PARCELS · SCHOOLS · DEMOGRAPHICSAggregated trends by city, county, and zip — price series, inventory, and days-on-market signals. Clean enough to feed AVMs, portals, and analytics products.
AVM-GRADE · MARKET-WIDEPropData is built on RESO — the Data Dictionary and Web API the real-estate industry already standardizes on. Your integration speaks the industry's native language from day one, over whichever surface fits the task.
Every board speaks its own dialect — status codes, field names, property types. PropData normalizes all of it to the RESO Data Dictionary, so one integration works everywhere we have coverage, and your code never learns a local dialect.
DATA DICTIONARY 2.1 · STANDARD ENUMSThe full OData query surface: filter, select, order, expand, and page — the skills your team already has transfer directly. Geospatial filtering is built in, by radius, bounding box, or polygon, for map-driven products.
$FILTER · $EXPAND · GEO.INTERSECTSThe same data over plain REST and JSON — camelCase fields, predictable resources, nothing to learn. Lighter for product work, friendlier for quick scripts. Use both, interchangeably, against the same catalog.
REST · JSON · INTERCHANGEABLEStandards where you want them. Simplicity where you don't.
Comprehensive, continuously refreshed MLS data is the raw material of prop‑tech. Teams use PropData to power IDX websites, national portals, iBuying models, tenant screening, and market analytics — without maintaining a single board relationship.
