Real estate data.
Institutional grade.
$49/mo.
Rent estimates, days on market, active inventory, price per sqft, and AI-computed investor signals for every ZIP in America. Replace RentCast. Build something real.
Three sources.
One response.
PropData aggregates HUD, Zillow Research, and Realtor.com — sources institutional investors pay thousands per month for — normalizes them, and serves them in a single API call. Flat monthly rate. Zero per-call fees. Ever.
Fair Market Rents
The government's official rent benchmark — the same data used to set Section 8 voucher amounts. Every county in America. Studio through 4-bedroom. Ground truth for affordability analysis.
Observed Rent Index
ZORI — Zillow's smoothed median asking rent for all homes and multifamily. The most cited rent trend dataset in real estate. ZIP, metro, state, and national with 10 years of history.
Market Metrics
Monthly listing data: median prices, days on market, active inventory, new listings, price reductions, price per sqft. The pulse of the for-sale market at ZIP level.
Built on Cloudflare.
Zero cold starts.
Global edge.
PropData runs on 5 dedicated Cloudflare Workers with a shared KV cache and Supabase backend. Every ingestion worker runs on its own cron — HUD weekly, ZORI and Realtor monthly. Data is cached at the edge and served in under 50ms anywhere in the world. This is the same infrastructure stack powering PropTechUSA.ai's 101 production Workers.
5 Cloudflare Workers
One per data source, one unified API layer, one site worker. No monolith. Clean separation.
KV Edge Cache
All market data cached at Cloudflare's edge. 7-day TTL. Sub-50ms reads globally.
Supabase Canonical Store
7 normalized tables. HUD FMR, ZORI zip/state/metro, Realtor zip/state/metro. Indexed for fast queries.
API Key Auth + Rate Limiting
Tiered access. Free 50/hr, Pro 500/hr, Internal unlimited. Keys provisioned in KV instantly.
Merged data.
Computed signals.
Every /v1/market response includes a signals array — investor intelligence automatically computed from the merged dataset. Gross yield, market velocity, inventory pressure. Not just raw numbers. Answers.
Rent + listing + signals — one response
Fastest endpoint for rent-focused apps
