money-transfer-api

Design

This app has 4 endpoints:

1. GET /user/<nick> - get user information by nick
2. GET /user/<nick>/withdraw?sum=<sum> - withdraw any sum of money
3. GET /user/<nick>/contribute?sum=<sum> - contribute any sum of money
4. GET/user/<nick>/transfer?sum=<sum>&to=<nick> - transfer money between users

It is also assumed that:

• there is no currencies, exchange rates, transactions, only abstract sums of money
• each user is an account itself
