Two prototype/sample projects - PHP/ REST API/ WebPage

I have two projects (each for less than $30) where I need to do proof of concept (mainly viability check) if something is possible or not. Project A) get 4 URLs from 4 products (in catalog in different websites), combine them in one product catalog web page (iframe or embedded object) and then we call our REST API to back end. If you prove you can do it, next we make it a longer project to design/ develop professional product catalog which allows one to source products from many web sites. Project B) I have 9 API test programs in PHP using Curl (each is less than 100 lines). Each test program works fine on command line and uses hardcorded key=value pair parameters to pass to end point as part of REST API. I want to combine all 9 programs in one script which takes input at run time and executes all programs one after another. We modify output at the end to show final results, overall success.
