99.co API: Singapore property data for search and investment apps

Singapore is a compact but highly liquid property market, split between the public HDB segment and the private condo and landed market. Buyers and renters filter heavily by MRT access, school proximity, and new launch availability. 99.co is one of Singapore’s leading property portals, and the 99.co Singapore API gives you structured access to its listings, projects, transactions, and agent data.

What the 99.co API covers

Property search - filter sale and rental listings across condos, HDB flats, landed homes, and apartments. Pull full listing details by ID or directly from a 99.co listing URL, and retrieve comparable listings for “similar homes” features.

New launch and projects - browse new launch and upcoming developments with price ranges, then get full project detail including facilities, floor plans, and active sale and rent units. New launch tracking is a core Singapore use case.

Nearby amenities - MRT stations, schools, supermarkets, and parks for a project, with walk, drive, and taxi commute times.

Transactions and trends - sold and rental transaction history for a project, area, or district, plus price trends and summary statistics for charts and valuation tools.

Agent directory - search agents and pull public profiles with contact details and listing breakdowns.

Querying the 99.co API

  new URLSearchParams({

    property_type: 'condo',
    min_price: '3000',

// listings with price, size, MRT proximity, project info, and agent details

Use the autocomplete endpoint first to resolve a location or project name to the IDs the search endpoints expect.
