Real estate data API with 50M+ deduplicated listings
Granular access to 50M+ properties with filters for precise location, architectural features, budget range, property type and transaction type.
Ranked comparable listings (comps) and median/average price per square metre with historical indices to power AVMs and appraisals.
Webhook notifications fire the moment a listing appears or a price changes, removing the need for polling.
Algorithms merge multiple listings for the same property into one clean record, with multi-source pricing history and publisher intelligence attached.

One key for 4,100+ agent tools, pay per call
A single treg token routes to 4,100+ endpoints across 127 providers, so no per-provider signups or scattered key files.
See each provider's price plus measured success rate, speed, and last-answer time, and pin a preferred vendor when you want.
Pay fractions of a cent per call with the price shown before you commit, no monthly seats required.
Route calls through your existing provider keys at no markup; credentials are injected server-side and never stored on a machine.
