Introduction of Rate Limits for API Usage

We would like to inform you that from 01.07.2025 a new rate limit for our APIs will be introduced.

What does this mean for you?

  • Rate limit: The rate limit determines how many API requests can be made within a certain period of time. From 01.07.2025, a maximum there is a certain limit within 5 minutes.
  • Monitoring: Our systems continuously monitor the number of requests. If the limit is exceeded, further requests will be blocked until the period expires.
  • Error messages: If the limit is exceeded, you will receive an error message with an HTTP status code of 429 (Too Many Requests). This message contains information about when you can make new requests.

Technical details:

  • Rate limiting mechanism: We use a token bucket algorithm to regulate the requests. Each API key receives a certain number of tokens that renew every 5 minutes.
  • Retry header: The error message will include a Retry-After header that indicates how long you need to wait before you can make further requests.
  • API Documentation: Please review our updated API documentation for detailed information and best practices to optimize your requests.

Advantages of the rate limit:

  1. Stability and reliability: The rate limit ensures that our APIs remain stable and reliable, even when demand is high. This prevents overloads and outages that could result from too many simultaneous requests.
  2. Even distribution: The rate limit ensures that all users have equal access to our APIs. This prevents individual users or applications from over-consuming resources and interfering with other users.
  3. Error messages and transparency: If the limit is exceeded, you will receive clear error messages that tell you when you can make new requests. This will help you better plan and optimize your requests.

Future improvements:

  1. More precise and meaningful rate limits: Over the course of the year, we will continue to refine the rate limits to make them even more tailored to the needs of our users. This means that we can make the limits dynamic, based on actual usage and requirements.
  2. Easy scalability: The new rate limits will be designed to be easily scalable. This allows our partners to flexibly expand their applications and services without encountering limitations.
  3. Optimized performance: The more precise rate limits allow our partners to take better advantage of optimized performance. This results in faster response times and an overall better user experience.

We are convinced that these measures will help to further improve the quality and reliability of our APIs and enable you to get the most out of them.
