Vietnamese property data is hard to trust at API speed.

Listings are inconsistent.

Prices, locations, property types, ownership details, and source fields vary across agents and platforms. Every product team ends up rebuilding the same normalization layer before they can ship anything useful.

Market context is missing.

An asking price means little without state land-price references, planning signals, boundary data, coordinate quality, and provenance. Without those signals, your platform cannot explain what users should compare or verify.

AI answers are only as good as the data underneath.

A chatbot over messy listings can sound certain without evidence. Your users need answers grounded in structured listing data, cited sources, and visible gaps.

bds.chat solves the data layer first: standardize listings, attach official references, compute data-trust grades, expose gaps, and let AI answer only from structured, cited context.

One API layer for standardized real estate intelligence.

1
Standardized listing schema
Search real HCMC listings through a normalized API designed for interoperability. Fields align with international standards including RESO, ISO 4217, ISO 3166-2, and GeoJSON.
2
State Price Context
Compare your listings against 30,771 HCMC state land-price records from NQ 87/2025, with market-to-state ratios and citable provenance. Reference only, not a market valuation.
3
Transparent trust reports
Your platform can display an A-F data-trust grade, 9 risk subscores, 5 blocking risk flags, data coverage, warning flags, and source-level provenance for each listing.
4
Scoped listing chat
Add listing-scoped AI answers without building your own RAG pipeline. POST /listings/{id}/chat streams responses from structured listing data, with citations and visible limits.
Instead of building ingestion, schema normalization, government price matching, trust scoring, citation tracking, auth, rate limits, and streaming AI yourself, integrate the API layer already built for Vietnam real estate.

Inspect a Trust Payload

Select a listing, review its trust report, compare the asking price to state land-price records, then ask a scoped AI question grounded only in that listing.
