Call /v1/exec to run the code in a sandbox:

POST http://localhost:1313/v1/exec
content-type: application/json

{
    "sandbox": "python",
    "command": "run",
    "files": {
        "": "print('hello world')"
    }
}

sandbox is the name of the pre-configured sandbox, and command is the name of a command supported by that sandbox. See Adding a sandbox for details on how to add a new sandbox.

files is a map, where the key is a filename and the value is its contents. When executing a single file, it should either be named as the command expects, or be an empty string (as in the example above).

Response:

HTTP/1.1 200 OK
Content-Type: application/json

{
  "id": "python_run_9b7b1afd",
  "ok": true,
  "duration": 314,
  "stdout": "hello world\n",
  "stderr": ""
}

• id is the unique execution identifier.
• ok is true if the code executed without errors, or false otherwise.
• duration is the execution time in milliseconds.
• stdout is what the code printed to the standard output.
• stderr is what the code printed to the standard error, or a compiler/os error (if any).
