process

Execute a command

Execute a command and return process information.

Streaming: with Accept: application/x-ndjson (or Accept: text/event-stream, kept for compatibility) the response is NDJSON (Content-Type: application/x-ndjson), not SSE: one JSON object per line, {"type": "...", "data": "..."}. type is stdout or stderr (data is a raw output chunk, sent as soon as the process writes it, newlines included; if the process finished before any chunk was streamed, its output is sent instead as one event per line, without the newline), keepalive (every 5 seconds, no data), error (data is the message, ends the stream) or result (last event, data is the ProcessResponse as a JSON string).

Authorizations

Authorization

string

header

required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Body

application/json

Process execution request

command

string

required

Example:

"ls -la"

callbackSecret

string

Key the webhook is signed with (HMAC-SHA256, X-Blaxel-Signature header). At least 32 characters; required with callbackUrl. Never returned by the API.

Example:

"a-random-secret-of-at-least-32-chars"

callbackUrl

string

URL that receives a signed process.exited webhook when the process ends for good (not on auto-restart). Requires callbackSecret.

Example:

"https://example.com/hooks/process"

env

object

Show child attributes

Example:

{ "{\"PORT\"": " \"3000\"}" }

keepAlive

boolean

Disable scale-to-zero while process runs. Default timeout is 600s (10 minutes). Set timeout to 0 for infinite.

Example:

false

maxRestarts

integer

Maximum number of restarts on failure. Set to a negative value (e.g. -1) for unlimited restarts.

Example:

3

name

string

Example:

"my-process"

restartOnFailure

boolean

Example:

true

stdin

boolean

Open a writable stdin pipe, fed via POST /process/{identifier}/stdin and closed via DELETE. The pipe does not survive a sandbox-api restart: the process then sees EOF.

Example:

false

timeout

integer

Timeout in seconds. When keepAlive is true, defaults to 600s (10 minutes). Set to 0 for infinite (no auto-kill).

Example:

30

waitForCompletion

boolean

Example:

false

waitForPorts

integer[]

Example:

[3000, 8080]

workingDir

string

Example:

"/home/user"

logs

string

required

Example:

"logs output"

name

string

required

status

enum<string>

required

Available options:

failed,

killed,

"stdout output"

workingDir

string

required

Example:

"/home/user"

keepAlive

boolean

Whether scale-to-zero is disabled for this process

Example:

false

maxRestarts

integer

Example:

3

restartCount

integer

Example:

2

restartOnFailure

boolean

Example:
