Sail SDK
Python client library for Sail, the most cost-efficient infrastructure provider for long-horizon agents.
Documentation
- Sail documentation: quickstarts, guides, and examples.
- Sailbox Python guide and Python API reference.
- Other languages: TypeScript, Rust.
Installation
Install the package with pip:
pip install sail
Or with uv:
uv add sail
Installing the SDK also puts the sail CLI on your PATH. To install the CLI on
its own, without the Python SDK, use the standalone installer:
curl -fsSL https://cli.sailresearch.com/install.sh | sh
For Python SDK scripts, CI, and headless agents, set an API key explicitly:
export SAIL_API_KEY=sk_...
What's inside
The SDK covers Sail's three surfaces: hosted inference
(sail.inference), Sailboxes (sandboxed VMs for agent workloads,
sail.Sailbox), and Voyages, automatic telemetry that records an agent
run as a trace of named agents, spans, events, and attributed model calls
(sail.voyage). See the Sail documentation
for quickstarts and API guides.
