Throttling Rates
To ensure fair usage and consistent performance, we enforce rate limits on the number of requests that can be made within a specific timeframe. This also ensures as many API users as possible have the opportunity of using the API without slowdowns.
If the limit is exceeded, subsequent requests will fail and you will receive a 429 Too Many Requests error in your responses.
The following table outlines the rate limits for different APIs:
| API | Rate Limit |
|---|---|
| Data Catalogue | 4 requests per minute |
| OpenDOSM | 4 requests per minute |
| Weather | 4 requests per minute |
| GTFS Static | 4 requests per minute |
| GTFS Realtime | 4 requests per minute |
