got "Too many requests error ···” message, but I only use it today

[Tangmissmoon]

I deployed the service on CloudFlare as instructed in the readme, but I haven't managed it for two months.
Today, when I requested it for the first time, I found this response. Was my service requested multiple times? Or is it the requested interface by others?
{ "query": null, "results": [], "message": "Too many requests error from IMDB, please try again later" }

Is there any way to improve this? Please help me. Thanks
