unsandbox.
Required Dependencies

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

  • HTTP.jl
  • JSON.jl

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 (Julia)

using HTTP
using JSON

api_key = get(ENV, "UNSANDBOX_API_KEY", "unsb-sk-test0-vault-unlck-12345")
url = "https://api.unsandbox.com/execute"
headers = Dict(
    "Content-Type" => "application/json",
    "Authorization" => "Bearer $api_key"
)
payload = JSON.json(Dict(
    "language" => "julia",
    "code" => "println(\"Hello from unsandbox!\")"
))

response = HTTP.post(url, headers, payload)
result = JSON.parse(String(response.body))

if result["success"]
    println("Output: ", result["stdout"])
else
    println("Error: ", result["error"])
end

Response (Success)

{
  "success": true,
  "stdout": "Hello from unsandbox!\n",
  "stderr": "",
  "error": null,
  "language": "python",
  "exit_code": 0
}

Response (Error)

{
  "success": false,
  "error": "Syntax error in code",
  "stderr": "SyntaxError: invalid syntax\n"
}
unsandbox.
POST https://api.unsandbox.com/execute/async

Submit code for execution and receive a job ID to poll for results. Best for long-running scripts or when you need to decouple submission from execution.
