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

language

enum<string>

required

Available options:

python,

node

code

string

required

Snippet source. Multi-line via \n in the JSON string.

timeout_seconds

integer

Required range: 1 <= x <= 300

cwd

string

env

object

Extra environment variables for this snippet only. Same semantics as env on /exec, per-call override on top of the sandbox's default environment.

Show child attributes

Example:

{ "OPENAI_API_KEY": "sk-..." }

stream

boolean

When true, the response is SSE (text/event-stream) as the snippet runs, same behaviour as /exec with stream: true.

Response

Code completed.

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

message

string

required

Example:

"Exec completed"

Upload a fileStreams the raw request body to the destination path inside the sandbox. **Body is the file bytes, not JSON, not multipart, not form-data.** The parent directory must already exist; the server does **not** `mkdir -p`. Size cap: 50 MB by default (`SANDBOX_MAX_FILE_SIZE_BYTES`). Include `Content-Length` so oversize uploads are rejected before the body is read.
