Singapore Open Data APIs: What They Can Do for Your Business
Singapore's free government data covers weather, maps, transport, property and population. Here's what each source offers and how businesses actually use it.
Frequently asked questions
What free government data can a Singapore business use?
The main sources are data.gov.sg (thousands of datasets plus live NEA weather and air-quality feeds), OneMap from the Singapore Land Authority (addresses, postal codes, travel routes, planning areas and population figures), LTA DataMall (bus arrivals, carpark lots, traffic incidents and monthly passenger volumes), URA's data service (private property transactions, rentals and URA carparks) and SingStat Table Builder for official statistics. All of them are free to use.
Can I use Singapore open data for commercial purposes?
Yes. The Singapore Open Data Licence, which covers data.gov.sg datasets, explicitly allows commercial and non-commercial use, including copying, adapting and redistributing the data. In return you must credit the source clearly, and you must not suggest the government endorses your product. Some services, such as OneMap and LTA DataMall, add their own terms of service on top, so read those too.
Do I need to credit data.gov.sg or OneMap on my website?
Yes. The Singapore Open Data Licence requires a conspicuous notice acknowledging the source of the data, and it gives a template naming the dataset, the date accessed and the licence. OneMap separately requires its logo and attribution wherever its base map is shown. A small 'Data sources' line in your footer or on the feature itself usually covers it.
What business problems can Singapore open data actually solve?
The most common ones are telling customers whether you serve their postal code, giving realistic delivery or arrival times, adjusting promotions or staffing to the weather, choosing where to open or advertise using passenger volumes and population by planning area, and sizing a market with official statistics. It works best when it removes a question customers already ask you on WhatsApp.
Is government open data reliable enough to build a customer-facing feature on?
It is authoritative, but it comes with no guarantee. The licences and terms state the data is provided 'as is' and 'as available', and the agencies can change or suspend services at any time. Treat it like any outside supplier: plan a sensible fallback, such as showing a general message or routing to a human, for the moments when a feed is late or unavailable.
How does Onz use Singapore government data?
Onz (onz.sg), Rampage Connect's own events site, has a planner called My Day that turns a one-line request into a day of real events, meals and travel times. It uses live NEA weather so outdoor plans make sense, and OneMap travel times so stops are reachable in the gaps between them. Its halal mode only suggests MUIS-certified options.
