Usage Process
Apply for your exclusive key
Contact the administrator and add the key
Access interface.
Usage Mode
- Add ("x-apikey", yourapikey ") to the request header.
Speed Limit Rules
The limit of access times is determined according to the user's role. Different roles set different access times (for example, free 500 times a month, common 10000 times a month, VIP unlimited times).
The access rate limit is determined according to the user's role. Different roles set different access rates (for example, free 60 times per minute, common 1000 times per minute, VIP does not set the limit).
