Develop a small API on node.js

Objective: To develop an API that can automatically select and use a proxy server based on geographic location.

Description of the task:
The API will use a third-party service to find the desired proxy server.
The service is called ProxyRental.
I have attached an example of a ready-made class in PHP to use this service.


The API will have one geo_request interface and will work on the following principle:
1. The client makes the request by POST method with the parameters specified below.
2. The API script sends geo. Information to ProxyRental service, it returns the IP address of the appropriate proxy server
3. Load the specified page through this proxy and return body + proxy data to the client

Input:
Country Country
State State State
City City
Url (HTTP or HTTPS URL to be processed)
Request_method (GET, PUT, POST, etc.)
Headers (an array of HTTP headers)
Body (data for HTTP body [optional])

Extradition:
Geo_ip (IP proxy server that will be used)
Geo_country (the country in which this proxy is located)
Geo_city (the city where this proxy is located)
Status (HTTP code)
Body (response body URL downloaded via proxy)

For the selected candidate, I will provide access to the ProxyRental account.

It is preferable to build an API on node.js + Hapi.js, but another library will also decline.

Please send the answer to the cost and time.

Thank you!
