Rest APIs without curl in shell script

We are not allowed to install curl on our linux box. Is there any other way to talk to Rest API's in shell script rather than using curl ? - Please advise - thank you

You can try with wget ; but it's quite the hard way.

thanks balajesuri, but i need to perform rest api's functions, click,upload,etc
do you think of any other alternative

You can use socket in/out using ksh93.
If you have ksh93 then it's possible todo http requests. Not so easy but it's possible.

Also it's possible using php or perl or python or ...
