API Rate Limits

To maintain fair use, protect against system abuse and maintain system reliability of our APIs, data.gov.sg has rate limits for these following API services:

• v2 Real-time APIs

• Dataset Downloads

While these APIs are free to use, the rate limit is significantly lower for users who are not logged in. For production use, we highly recommend signing up on our platform to access higher rate limits.

Rate Limits

The rate limits are reset every 10 seconds - the following rate limits represent the number of API calls that can be made every 10 seconds.

API Endpoint	Without API Key	With Dev API Key	With Prod API Key
v2 Realtime API	6	12	30
Dataset Downloads	2	4	10

Tier Definitions

• Without API Key: Public access. Lowest limits for exploration.

• Development Tier (Dev): Requires API Key. Moderate limits for development/testing purposes.

• Production Tier (Prod): Requires API Key. Highest limits, priority support for your application.

We are currently fine-tuning these rate limits based on user inputs and would appreciate receiving your feedback at [email protected].
