Requests are limited based on the token, not the IP address.
Example:：
The basic plan allows 1 request per second.
If a token requests the /kline API at 14:03:01 and the /trade-tick API within the same second, both will be processed.
However, if the token sends two requests to /kline at 14:03:01, the first will succeed, but the second will be rejected.
/kline API:
Queries must specify one product code per request.
A maximum of 1,000 K-line records can be returned per request.

Supports multiple product codes per request.
The number of codes allowed depends on the purchased plan.
Each request returns up to 2 K-line records per code.
