Why Choose Our Centaline Property API

In a dense high-rise market, the block and floor are the listing.

Between block-and-floor-level historical transaction records that Hong Kong's estate-based housing market depends on, the Centa-City Index that serves as the territory's benchmark residential price gauge, and mortgage rate comparison data tied to specific listings, Centaline's catalog carries more granular transaction and index structure than a standard listing feed. Our infrastructure absorbs that complexity so your team just calls an endpoint and gets data back.

01

Zero blocking, zero maintenance

We run rotating residential IPs, headless rendering, and CAPTCHA-solving behind every request. When Centaline changes its layout, we patch our parsers — your integration never breaks.

02

Block/floor aware

Every estate response resolves down to block, floor, and unit level rather than treating a listing as one flat address.

03

CCI & mortgage detail

We resolve Centa-City Index values and mortgage rate comparisons with the same structured fields as core listing data.

04

Built for scale from day one

From a 100-listing test batch to millions of daily checks across Hong Kong, mainland China, and Macau, the same endpoint and response shape scale with you.
