unsandbox.
Required Dependencies

The Nim examples below require the following 3rd party libraries:

  • httpclient
  • json

Make sure these packages are installed in your environment before running the examples.

unsandbox.
POST https://api.unsandbox.com/execute

Execute code immediately and wait for results. Best for quick scripts and interactive use.

Request Parameters

Parameter Type Required Description
language string Programming language
code string Source code to execute
env object Environment variables (key-value pairs)
network_mode string "zerotrust" or "semitrusted"
ttl integer Timeout 1-900s (default: 60)
return_artifact boolean Return compiled binary
return_wasm_artifact boolean Return WebAssembly binary

Example (Nim)

import httpclient, json

let client = newHttpClient()
client.headers = newHttpHeaders({
  "Content-Type": "application/json",
  "Authorization": "Bearer getEnv("UNSANDBOX_API_KEY", "unsb-sk-test0-vault-unlck-12345")"
})

let payload = %* {
  "language": "nim",
  "code": "echo \"Hello from unsandbox!\""
}

let response = client.postContent("https://api.unsandbox.com/execute", $payload)
let result = parseJson(response)

if result["success"].getBool:
  echo "Output: ", result["stdout"].getStr
else:
  echo "Error: ", result["error"].getStr

Response (Success)

{
  "success": true,
  "stdout": "Hello from unsandbox!\n",
  "stderr": "",

  "success": false,
  "error": "Syntax error in code",
  "stderr": "SyntaxError: invalid syntax\n"
}
