Lizard Python SDK
Run commands, work with files and execute code in Linux sandboxes on Kubernetes. The SDK also manages Lizard apps, databases, storage and projects.
Install
Requires Python 3.10+. The Python client is synchronous.
pip install lizard-sdk
Create an API key and project at lizard.build, then set:
export LIZARD_API_KEY="your-api-key"
Create a sandbox
Save this as quickstart.py. Replace my-project with your project's ID, slug or unique name, then run python quickstart.py.
from lizard import Lizard
lizard = Lizard(project="my-project")
with lizard.create("base", timeout_ms=300_000) as sandbox:
sandbox.fs.write("/tmp/hello.txt", "Hello from Lizard!")
result = sandbox.process.exec_("cat /tmp/hello.txt")
if result.exit_code != 0:
raise RuntimeError(result.stderr)
print(result.stdout)
The context manager kills the sandbox when the block ends, including when it raises an error. If you create a sandbox without with, call sandbox.kill() in a finally block.
Stream command output
Inside the with block above:
result = sandbox.process.exec_(
'printf "hello\\n"',
timeout_ms=30_000,
on_stdout=lambda chunk: print(chunk, end=""),
on_stderr=lambda chunk: print(chunk, end=""),
)
if result.exit_code != 0:
raise RuntimeError(result.stderr)
Run code
CodeSandbox uses the code-interpreter-v1 template by default. Code errors appear in result.error; request failures raise an exception.
from lizard import CodeSandbox
with CodeSandbox.create(project="my-project") as sandbox:
result = sandbox.run_code(
"print(6 * 7)",
language="python",
timeout_ms=60_000,
on_stdout=lambda chunk: print(chunk, end=""),
)
if result.error:
raise RuntimeError(result.error.message)
Configuration
The SDK reads LIZARD_API_KEY and, optionally, LIZARD_API_URL (default: https://lizard.build). You can also pass api_key and api_url to the constructor or static sandbox methods.
Pass timeout_ms to create() to set the sandbox lifetime. The default is five minutes. timeout_ms on process.exec_() or run_code() controls that call, not the sandbox lifetime.
Runtime limits
Sandboxes run on Kubernetes. Use volumes mounted at /workspace to keep files after a sandbox ends. Pause, resume, fork, snapshot creation and snapshot restore return HTTP 501 on the current backend.
get_host() returns a hostname without https://. File writes accept UTF-8 text or valid UTF-8 bytes; read_bytes() supports binary downloads.
