You need a root key with the permissions listed on this page. Create one in the dashboard under Settings > Root Keys. See Permission reference for every permission.
Retrieve one of an , including its build, runtime, health check, and region settings. Each of --project, --app, and --environment takes an ID or a slug.

Usage

Flags

string
required
App ID or slug.
string
required
Environment ID or slug, for example production or preview.
string
required
Project ID or slug. Both forms resolve to the same project.

Shared flags

Every unkey api command accepts these; CLI output and shared flags describes them in full.
string
A JSON document sent as the request body instead of building it from the flags above. It is mutually exclusive with the request-building flags, and unknown fields are rejected locally. See Send a raw body.
string
Root key for the request. Falls back to UNKEY_ROOT_KEY, then to the config file written by unkey auth login. See CLI authentication.
string
default:"https://api.unkey.com"
Base URL of the API. Falls back to UNKEY_API_BASE_URL. You don’t normally need to set it.
string
default:"~/.unkey/config.toml"
Path of the TOML file that unkey auth login writes. Falls back to UNKEY_CONFIG.
string
Output format. Falls back to UNKEY_OUTPUT. Set json to print the full response envelope (meta and data) for piping; any other value prints the request ID followed by data.

Required permissions

Your root key needs one of:
  • environment.*.read_environment (any environment)
  • environment.<environment_id>.read_environment (a specific environment)
If the environment doesn’t exist or your key doesn’t have the permission, you get the same 404: The requested environment does not exist. See Root key permissions for the full catalog.

Examples

Get the production environment:
Print only the runtime settings:

API endpoint

The command calls POST /v2/environments.getEnvironment and prints its response. The request fields carry the same names as the flags in camelCase, which is the shape --body expects.
