The Steuerboard API has a rate limit of 60 requests per minute. If you exceed the rate limit, you will receive a 429 response error.

​
Response Headers

The response headers describe your current rate limit following every request in conformance with the sixth IETF standard draft:
Header nameDescription
ratelimit-limitMaximum number of requests allowed within a window.
ratelimit-remainingNumber of requests remaining within a window.
ratelimit-resetTime at which the rate limit will reset.
retry-afterHow many seconds you should wait before making a follow-up request.
To prevent this, we recommend reducing the rate at which you request the API. This can be done by introducing a queue mechanism or reducing the number of concurrent requests per second. If you have specific requirements, contact support to request a rate increase.
