A RESTful API which exposes two resources:

• /traces
• /statistics

This endpoint will receive, via HTTP POST, an IP address in the format 100.100.100.100, and return the following information associated with that IP address:

• Country which issued the IP and its ISO code
• Coordinates for its location (latitude and longitude)
• An array of currencies for that country with:
• ISO code (USD, CAD, ARS)
• Symbol ($, £)
• Conversion rate from currency to USD
• Distance between United States and country of origin (in Kilometers)

A resource which, on an HTTP GET, returns:

• Longest distance from requested traces
• Most traced country

• For each 3rd party API error, we are returning HTTP CODE 500 - Internal Server Error
• USA latitude & longitud are from Washigton DC (US Capital)
• We are using currency name as a symbol instead of currency symbol. ie: Argentinian Peso, not $ symbol.
• We are only caching GET Symbols endpoint (based on assignment recommendations)
• We created Docker config for future deploying.
• We are using config env variables. So, you need to configure them based on .env.sample file.
• We calculate distance (two point using lat,long) in Kms to USA using a well-known formula searched on Internet.
• Both resources body repsonses structure are not prettty equal to requested assigment due to GraphQL schema defined.
