To prevent excessive crawling of the data we make available and to ensure a good overall performance, requests to the API are subject to rate limits.
Each IP is allowed to perform 100 requests per minute. We observe the usage and user requirements and may adjust this if needed. At the moment, IPs can make new requests as soon as the number of requests within the last minute sinks below 100 again (so you do not get blocked for a certain amount of time).
To reduce the amount of requests you make, consider:
- embedding resources or
- increase the amount of elements per page in a collection to the maximum allowed value (200).
When you reached your request limit, the API will respond with the HTTP status code 420.
If you need to make more requests than allowed, contact us and we can find a solution.
