Hi Sir,
I'm a web developer and PHP programmer.
I can modify the script according to your needs, to use multiple keys.
If a keys is getting blocked after too many request is made using that key, then WHAT is the response Taking that into account , a trigger function can be made to switch the key to be used in the script.
I can write the script easily and efficiently in less time, please check my profile reviews for my work quality.
Thank you
