ProjectEulerAPI

Lets you can programmatically check your solutions!

Not complete!

This API does not use Project Euler's backend, so it needs solution contributions!

The currently known solutions are in app/data/solutions.txt. If you have a solution to add, please fork this repo, add it to the list, and make a pull request!

Here is a guide on how to fork and make a pull request: https://www.digitalocean.com/community/tutorials/how-to-create-a-pull-request-on-github

How to use

This is a REST API, which basically means you send an HTTP request to check your solution.

cURL

# To send the request to check if the solution for Problem 1 is 2.
curl -X GET 'http://www.projecteulerapi.com/api/problem/1/check/2'
# The response is in the JSON format
# {"status":200,"result":"incorrect","error":null}

Ruby

using the HTTParty gem

require 'HTTParty'
# need to run `gem install HTTParty` if you don't have it already

response = HTTParty.get 'http://www.projecteulerapi.com/api/problem/1/check/2'
puts response.parsed_response['result']
#=> incorrect

Javascript (Node)

using the axios library

const axios = require('axios')
// need to run `npm install --save axios` if not already in your project

axios.get('http://www.projecteulerapi.com/api/problem/1/check/2')
     .then((response) => {
       console.log(response.data.result)
     })
     .catch((error) => {
       console.log(error)
     })
//=> incorrect

Elixir

using the HTTPotion and Poison Hex packages

# requires HTTPotion and Poison to be dependencies in your mix.exs file

"http://www.projecteulerapi.com/api/problem/1/check/2"
|> HTTPotion.get
|> Map.get(:body)
|> Poison.decode!
|> Map.get("result")
|> IO.inspect

#=> incorrect
