Authorizations

x-brimble-key

string

header

required

Your account-level Brimble API key. Find it in the dashboard under your profile drawer → API key (click the avatar in the sidebar). Available on paid plans only.

Path Parameters

string

required

24-char hex id of the sandbox.

Pattern: ^[a-f0-9]{24}$

Body

application/json

cmd

string

required

Shell command to run. Pipes / && / redirects all work.

timeout_seconds

integer

Defaults to 30. Process is killed at the limit.

Required range: 1 <= x <= 300

cwd

string

Absolute path inside the sandbox. Defaults to /.

env

object

Extra environment variables for this command only. Layered on top of the sandbox's existing environment; same-named keys here override the sandbox-level ones for this call. Values must be strings. Scoped to a single invocation, the next call starts with the sandbox defaults again.

Show child attributes

Example:

{
  "NODE_ENV": "production",
  "DATABASE_URL": "postgres://..."
}

stream

boolean

When true, the server keeps the connection open and streams stdout/stderr as Server-Sent Events (text/event-stream). Each event is a JSON object on a data: line; the last event is always { "type": "done", ... } or { "type": "error", ... }.

Response

Command completed.

When the request body has stream: true, the response is text/event-stream, one ExecStreamFrame per data: event, the last being a done event.

message

string

required

Example:

"Exec completed"

object

Run a code snippetWrites `code` to a temp file and runs it with the chosen interpreter. Cleaner than `/exec` for multi-line scripts because you don't have to deal with shell escaping. Response shape matches `/exec`. Supports the same `stream: true` opt-in as `/exec`; see that endpoint's description for the SSE event shape.
