## Limitations

- All functions must be executed with a simple **HTTPS GET** request.
- The **API Key** should be provided as the authorization key in the request header. If the key is incorrect, the operation will not be executed, and an authorization error will be returned in the response.
- The service is subject to a rate limit of **25 requests per minute** to ensure optimal system performance. If you exceed this limit, you will receive an HTTP **429 Too Many Requests** response.

> The default limit shown here is a standard baseline. If your use case requires higher capacity, feel free to reach out to the Insider One team. We can adjust it to fit your needs.
