Sandboxes API

Create and manage isolated execution environments with full lifecycle, file system, snapshot, and checkpoint support.

Authentication

Most requests require a Bearer token. Pass your SDK key in the Authorization header. Public endpoints (such as listing and fetching public snapshots) are noted below and do not require authentication.

You can find your SDK key in the Agentuity Console under your project settings.
