}Limitations
- All functions must be executed with a simple HTTPS POST 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 100 requests per second to ensure optimal system performance, and clients exceeding this limit will receive an HTTP 429 Too Many Requests response.
