Anonymous remote code, compile, & execution API for humans & machine learning agents.
Docs 📚 View Pricing →The Nim examples below require the following 3rd party libraries:
httpclientjson
Make sure these packages are installed in your environment before running the examples.
Execute code immediately and wait for results. Best for quick scripts and interactive use.

}
Possible Status Values
pending- Job queued, waiting to executerunning- Job currently executingcompleted- Job finished (check result field)timeout- Job exceeded TTL limitcancelled- Job was cancelled via DELETE
List all active (pending or running) jobs for your API key. Useful for monitoring multiple async executions.
Example (Nim)
import httpclient, json
let client = newHttpClient()
client.headers = newHttpHeaders({
"Authorization": "Bearer getEnv("UNSANDBOX_API_KEY", "unsb-sk-test0-vault-unlck-12345")"
})
let response = client.getContent("https://api.unsandbox.com/jobs")
let jobs = parseJson(response)
for job in jobs:
echo job["job_id"].getStr, ": ", job["status"].getStr, " (", job["language"].getStr, ")"
Response
{
"jobs": [
{
"job_id": "job_1234567890_abc",
"status": "running",

"status": "pending",
"language": "go",
"submitted_at": "2024-01-15T10:29:45Z"
