CodeX Golang Example

Let's make http requests into CodeX api to see how we can work with CodeX. CodeX is a free api for executing codes. It provides two apis for getting the list of available programming languages and executing a code.

API

In order to execute a code, you need to send a post request to CodeX api.

• URL: https://api.codex.jaagrav.in
• Method: POST
• Body: query string

CURL

curl -X POST -H 'Content-type: application/x-www-form-urlencoded' -d 'query-string' https://api.codex.jaagrav.in

Query String

A query string is a set of characters tacked onto the end of a URL. The query string begins after the question mark (?) and can include one or more parameters. Each parameter is represented by a unique key-value pair or a set of two linked data items. An equals sign (=) separates each key and value.

Example

?foo=unicorn&ilike=pizza

CodeX QS

For your request body you should convert the following data to a query string.

Input

{
  "code": "print(int(input())+7)",
  "language": "py",
  "input": "5",
}

Convert to

code=value+%3D+int%28input%28%29%29+%2B+7%0Aprint%28value%29&input=5&language=py

JSON Response

{
  "timeStamp": 1676969214607,
  "status": 200,
  "output": "12\n",
  "error": "",
  "language": "py",
  "info": "Python 3.6.9\n"
}

Test

See the test example implemented in Golang.

Build

go build -o main

Run

./main -f example.py -e py -i 8
