# 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](https://data.gov.sg/datasets?formats=API)
* [Datastore Search](https://guide.data.gov.sg/developer-guide/dataset-apis/search-and-filter-within-dataset)
* [Dataset Downloads](https://guide.data.gov.sg/developer-guide/dataset-apis#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](https://data.gov.sg/?signin=Registration) 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. If the rate limits are exceeded, you will receive a `429` status error (Too many requests)

We are currently fine-tuning these rate limits based on user inputs and would appreciate receiving your feedback at <support@data.gov.sg>.&#x20;
