Start a process, stream its captured output over Server-Sent Events, and receive a final exit event. Use this endpoint when you want a single request for non-interactive command execution. If the process needs stdin, use Start Process, Process Stdin, and Close Process Stdin instead.

Endpoint

POST /api/v1/processes/run

Use this endpoint on the sandbox proxy host:

https://<sandbox-id-or-name>.sandbox.tensorlake.ai/api/v1/processes/run

Example Request

curl -N -X POST https://<sandbox-id>.sandbox.tensorlake.ai/api/v1/processes/run \
  -H "Authorization: Bearer $TENSORLAKE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "command": "python",
    "args": ["-c", "import os; print(os.environ[\"MODE\"])"],
    "env": {"MODE": "batch"},
    "working_dir": "/workspace",
    "timeout": 30
  }'

Request Body

{
  "command": "python",
  "args": ["-c", "print('hello')"],
  "env": {"MODE": "batch"},
  "working_dir": "/workspace",
  "user": "tl-user",
  "timeout": 30
}

command is required.
args defaults to [].
env defaults to {} and is applied to the process environment.
working_dir is optional.
user is optional and accepts a username, UID string, uid:gid string, or an object such as {"uid": 1000, "gid": 1000}.
timeout is optional. When set, Tensorlake kills the process if it is still running after that many seconds.

/processes/run always starts the process with stdin closed and stdout/stderr captured, even if stdin_mode, stdout_mode, or stderr_mode are present in the request body.

SSE Events

Tensorlake streams JSON payloads in SSE data: frames:

data: {"handle":1,"pid":42,"started_at":1710000000000}

data: {"line":"hello","timestamp":1710000000010,"stream":"stdout"}

data: {"exit_code":0}

The first event contains handle, pid, and started_at. Output events contain line, timestamp, and stream. The final event contains exit_code or signal; if the kernel OOM killer ended the process, it includes signal: 9 and oom_killed: true.
