One Map, Singapore Pricing: Free API Access (2026)

Pricing overview

One Map, Singapore, developed and maintained by the Government Technology Agency (GovTech) of Singapore, operates on a free-to-use model for all its API services. This includes core functionalities such as the One Map Search API, Geocoding, Reverse Geocoding, and Routing. The platform's objective is to provide accessible geospatial data and services for developers building applications relevant to Singapore, supporting both personal and commercial projects without direct charges.

There are no subscription fees, usage-based charges, or paid tiers associated with One Map, Singapore. The primary distinction in usage is between unregistered and registered users. Unregistered users can access basic APIs immediately without an API key, subject to default rate limits. Registered users obtain a free API key, which provides higher rate limits and access to certain enhanced APIs, facilitating more intensive application development and deployment.

The absence of direct costs simplifies budgeting for developers and organizations, as there are no variable expenses tied to API calls or data consumption. This model supports public services, educational initiatives, and commercial ventures within Singapore by removing financial barriers to geospatial data access.

Plans and tiers

One Map, Singapore does not implement a tiered pricing structure with different cost levels. Instead, it offers a singular access model with varying rate limits based on user registration status. This approach ensures that all users have access to the full suite of available APIs, with registration primarily serving to manage system load and prevent abuse.

Unregistered User Access

• Access: Immediate access to most basic APIs.
• Requirement: No registration or API key needed.
• Limits: Subject to default, lower rate limits. Specific limits are detailed in the One Map developer documentation. This tier is suitable for initial testing, small-scale personal projects, or applications with infrequent API calls.

Registered User Access

• Access: Full access to all APIs, including enhanced features.
• Requirement: Free registration and obtaining an API key.
• Limits: Higher rate limits compared to unregistered users. The increased limits accommodate more robust applications and higher traffic volumes. Registered users also gain access to specific APIs that might require an API key for operational reasons, such as certain data submission or complex query functions.

The registration process involves creating an account on the One Map developer portal and generating an API key. This key is then used in API requests to identify the application and apply the appropriate rate limits. There is no cost associated with this registration or key generation.

Free tier and limits

One Map, Singapore essentially operates as a comprehensive free tier for all its services. The platform explicitly states that it is "Free for personal and commercial use without registration for basic APIs. Enhanced APIs require registration." This means that the core functionality is always available at no cost.

The primary control mechanism for resource usage within this free model is rate limiting. These limits are designed to ensure fair usage and maintain the stability and performance of the One Map infrastructure for all users. While specific, up-to-date rate limits are subject to change and are best consulted directly in the One Map developer documentation, the general principle is:

• Unregistered users: Experience lower API call limits per unit of time (e.g., per minute or per hour). This is sufficient for casual exploration or development of non-intensive applications.
• Registered users with API keys: Receive significantly higher API call limits. This allows for the development and deployment of applications that require more frequent data retrieval or processing, such as interactive web maps with dynamic data updates or mobile applications with heavy location-based features.

The free nature extends to all types of usage, whether for educational purposes, individual hobby projects, or commercial applications developed by businesses operating in Singapore. There are no hidden fees or charges that activate after exceeding certain usage thresholds.

Real-world cost examples

Given One Map, Singapore's free pricing model, calculating "real-world costs" primarily involves considering factors other than direct API charges. The absence of per-request fees means that typical cost-per-call calculations, common with commercial mapping providers, are not applicable. Instead, developers and organizations budgeting for a project using One Map, Singapore will focus on:

1. Developer time: The cost of engineering hours spent integrating the APIs, designing the user interface, and maintaining the application. This is consistent across all API platforms.
2. Infrastructure costs: Expenses related to hosting the application, database services, and other cloud resources required to run the solution that consumes One Map APIs. For example, a web application might incur costs for a web server (e.g., Amazon EC2 instance) and a content delivery network (e.g., Cloudflare CDN) to serve static assets.
3. Data storage: If the application stores retrieved One Map data, such as cached geocoding results, there will be associated storage costs.
4. Support & maintenance: Ongoing costs for bug fixes, feature enhancements, and monitoring the application's performance.

Example Scenario: Small Business Directory

A small business in Singapore wants to create a simple web directory of local shops, integrating One Map's Geocoding API to display shop locations on a map and the Routing API to provide directions. The application is expected to serve up to 5,000 unique visitors per day, each making an average of 3-5 API calls (e.g., search, geocode, route).

• One Map API costs: S$0.00 (free for registered users, assuming usage within rate limits).
• Estimated non-API costs (monthly):
  • Web hosting (e.g., basic cloud instance): S$20 - S$50
  • Database (e.g., managed SQL): S$10 - S$30
  • Developer time (initial setup, minimal maintenance): Variable, but not tied to API usage.

The primary costs for this business would be related to their own infrastructure and development efforts, not the One Map API usage itself. The high rate limits for registered users would likely accommodate 5,000 daily visitors without issues.

Example Scenario: Public Transport Tracking App

A startup develops a mobile application that tracks public transport in Singapore, requiring frequent updates of vehicle locations and routing information using One Map APIs. The app is popular, with 50,000 active users making continuous API requests.

• One Map API costs: S$0.00 (free for registered users, assuming usage within rate limits).
• Estimated non-API costs (monthly):
  • Scalable cloud infrastructure (e.g., AWS Lambda, Google App Engine, Azure Functions for serverless backend): S$500 - S$2,000+
  • Managed database (high-performance): S$200 - S$800
  • Content Delivery Network (CDN) for map tiles/assets: S$50 - S$200
  • Developer/Ops team for maintenance and scaling: Significant, but not API-dependent.

Even with high usage, the One Map API itself imposes no direct cost. The budget would be dominated by the scaling of the application's backend infrastructure and operational overhead.

How the pricing compares

One Map, Singapore's free pricing model stands in contrast to the usage-based, commercial models typically employed by global geospatial API providers. This difference is a key factor for developers and organizations when selecting a mapping platform, especially for applications focused on Singapore.

For projects exclusively focused on Singapore, One Map's free model presents a significant cost advantage over commercial alternatives. While platforms like Google Maps Platform, Mapbox, and HERE Technologies offer broader global coverage, more advanced features, and potentially higher scalability for very large global deployments, their usage-based pricing models can lead to substantial costs as application usage grows. Developers must weigh the specific geographical scope and feature requirements of their project against the cost implications of each platform.

For instance, a Singapore-based application that only needs to display locations and provide directions within the city-state can leverage One Map's free services without incurring any direct mapping API expenses. If the application later expands to other countries, integrating a commercial provider for international data while continuing to use One Map for Singapore-specific features might be a hybrid solution. However, this introduces architectural complexity.

The free model also makes One Map an attractive option for educational institutions, non-profit organizations, and government agencies within Singapore, as it minimizes overhead and maximizes resource allocation towards application development rather than API licensing.
